CardioNerds Co-Founder Dr. Daniel Ambinder, Episode Chair Dr. Dinu Balanescu, and FIT Lead Dr. Natalie Tapaskar discuss advanced heart failure in CardioOncology with expert Dr. Richard Cheng. Audio editing by CardioNerds Academy Intern, Dr. Akiva Rosenzveig.
In this episode, we discuss the spectrum of advanced heart failure in patients with a history of cancer. We dissect cancer therapy-related cardiac dysfunction (CTRCD) cases and the imaging and biomarker tools available for risk stratification and disease monitoring. We delve into the data on the use of guideline-directed medical therapy (GDMT) and cardiac resynchronization therapy (CRT) in these patients. We discuss the risk of prior radiation and chemotherapy during cardiac surgery. Finally, we learn about the post-transplant risk of rejection, recurrent malignancy, and de-novo malignancies, as well as treatment strategies we can employ for these patients.

Pearls and Quotes – Advanced Heart Failure in CardioOncology
Use the HFA-ICOS risk tool to understand the baseline risk of developing cancer therapy-related cardiac dysfunction (CTRCD). Key factors are type of cancer therapy, baseline CV risk factors, and age.
A relative change in global longitudinal strain of more than 15% from baseline is a marker of early cardiac dysfunction and predicts the subsequent risk for systolic dysfunction in patients undergoing cardiotoxic chemotherapy.
Statins may be useful in prevention of cardiovascular dysfunction in patients receiving anthracycline chemotherapy. There is limited data on the 4 pillars of GDMT in prevention of CTRCD, but should be started early once CRTCD is suspected or diagnosed!
Mediastinal radiation causes adhesions and scarring which increase the risk of bleeding during cardiac surgery, lead to longer operative times, and can lead to RV failure and poor wound healing.
Patients with a pre-transplant history of malignancy have a higher risk of mortality due to post-transplant malignancy. And patients with active cancer should not be considered for heart transplant. Post-transplant malignancy risk can be mitigated by utilizing an mTOR based, CNI free immunosuppression regimen.
Show notes – Advanced Heart Failure in CardioOncology
How do cardio-oncology and advanced heart failure intersect?
There are 3 basic populations of patients to consider:
Patients with advanced heart failure who develop cancer.
Patients with pre-existing chemotherapy and radiation exposure for cancer treatment who later develop advanced heart failure
Heart transplant recipients who, in the long term are at very high risk of developing cancer
Cardio-oncologists must consider risk assessment and mitigation, long-term prognosis, and treatment strategies for each of these unique populations.
How can we assess the risk of developing cardiovascular disease during cancer treatment (CTRCD)?
There are many proposed risk tools. However, the majority are not well-validated.
One of the most used tools is the HFA-ICOS risk tool.1
You can select the planned cancer therapy for the patient (anthracyclines, HER-2, VEGF, RAF/MEK inhibitors, Kinase inhibitors, multiple myeloma therapies) and then calculate their risk of developing CV disease during cancer treatment based on baseline variables:
1) previous history of CV disease,
2) biomarkers – troponin and NT-proBNP
3)age,
4) CV risk factors -HTN, DM, CKD,
5) previous cardio-toxic treatments,
6) lifestyle risk factors- smoking, obesity
The risk tool will then give you a ranking of very high, high, medium, or low risks.
How should we use imaging to evaluate cardiac dysfunction in patients undergoing cancer treatments?
Echo with global longitudinal strainA relative change in global longitudinal strain of more than 15% from baseline is a marker of early cardiac dysfunction and predicts the subsequent risk for systolic dysfunction.Data are mixed on the benefit of intervening on drops in GLS without a concomitant drop in LVEF. Current vendor software has improved the consistency in GLS measurements across vendors, which used to be quite problematic.
Echo LVEF
Some centers prefer to use 3D LVEF to track patients over time.
For asymptomatic high-risk patients, we should obtain echocardiograms at 1, 3, and 5 years post-cancer therapies and then every 5 years thereafter.
But surveillance should occur on a case-by-case basis.
CPET
Can be used to risk stratify patients with lung or colon cancer before starting cancer treatment.
You can trend peak VO2 over time after cancer treatments.
However, this is generally a data-sparse zone!
Can we use serum biomarkers such as troponin or NT-proBNP in monitoring for the development of CTRCD?
Elevations in BNP during cancer treatment are associated with subsequent cardiovascular disease.
Elevations in troponin and myeloperoxidase in breast cancer patients receiving anthracyclines can predict the risk of cardiotoxicity.
Novel biomarkers – data-free zone
CRP is a marker of inflammation and may be helpful in patients undergoing radiation therapy.
Immunoglobulins- baseline elevated IgE levels have a lower risk for cardiotoxicity.
Cell-free DNA – may be the future?
What is the role of cardiovascular medications and devices in preventing and treating CTRCD?
Prevention:
Statins – The STOP-CA trial showed that use of atorvastatin 40 mg/day in patients with lymphoma receiving anthracycline chemotherapy reduced the incidence of cardiac systolic dysfunction compared to placebo.2
SGLT2i – limited retrospective data in patients with diabetes and anthracycline chemotherapy. May have lower rates of cardiac events on SGLT2i.
Currently there is not enough data to recommend routine use of SGLT2i, ARNI, and BB for cardioprotection before cancer therapies.
Treatment:
Treat these patients similarly to other heart failure patients. The four pillars of GDMT work! Early recognition is critical to confer better long-term outcomes.
CRT-D: MADIT-CHIC3 showed that CRT therapy improved LVEF at 6 months in patients with chemotherapy-induced cardiomyopathy.
Only consider ICD if life expectancy is >1 year.
There is a risk of device reset for radiation directly over the device. ICDs are more sensitive to ionizing radiation, leading to inappropriate shocks.
Can consider moving the device to a non-radiation field.
What do we need to consider when patients with a history of cancer are being evaluated for heart transplant and left ventricular assist device (LVAD)?
Heart transplant
Patients with chemo-induced cardiomyopathy have no differences in post-transplant outcomes compared to patients with other causes of cardiomyopathy.
Patients with a pre-transplant history of malignancy have a higher risk of mortality due to post-transplant malignancy, particularly in those with a history of hematologic malignancy.
Patients with active cancer should not be considered for heart transplant.
The duration and interval of waiting after active cancer before a heart transplant depends on the type and stage of cancer.
LVAD
Patients with chemotherapy-induced cardiomyopathy have similar outcomes and rates of post-LVAD RV dysfunction as patients with other etiologies of cardiomyopathy.
Limited data on performing LVAD in patients with active cancer.
What risk does prior mediastinal radiation pose to cardiac surgery?
Mediastinal radiation
Increases adhesions and scarring, increasing the risk of bleeding during cardiac surgery. Longer operative times may also increase the risk of RV failure.
There can also be atrophy of sternal muscles, which can lead to poor wound healing
What do the post-heart transplant rejection and malignancy profiles look like for patients with a history of chemotherapy-induced cardiomyopathy?
Patients with prior chemotherapy have depressed immunosurveillance from their innate immune system and, thus, may have a lower risk of rejection. But there is limited data here.
Patients with a history of pre-transplant malignancy are at increased risk of recurrence and PTLD. You can consider decreasing immunosuppression or switching to mTOR inhibitor-based regimen to reduce the risk.
What must we know about de-novo malignancy post-heart transplant?
Risk factors: history of prior malignancy, heavier immunosuppression, older recipient age, smoking history, radiation exposure, genetic variants.
Treatment: reduce immunosuppression as much as possible and switch to an mTOR-based regimen.
What about immune checkpoint inhibitors post-transplant?
These work by upregulating T cell activity, which counteracts our transplant immunosuppression. High risk of rejection, but some successful case reports of use.

April 22, 2024365: CardioOncology: Cardiotoxicity of Novel Immunotherapies with Dr. Tomas Neilan
Immunotherapy is a type of novel cancer therapy that leverages the body’s own immune system to target cancer cells. In this episode, we focused on the most common type of immunotherapy: immune checkpoint inhibitors or ICIs. ICIs are monoclonal antibodies targeting immune “checkpoints” or brakes to enhance T-cell recognition against tumors. ICI has become a pillar in cancer care, with over 100 approvals and 5,000 ongoing trials. ICIs can lead to non-specific activation of the immune system, causing off-target adverse events such as cardiotoxicities. ICI-related myocarditis, though less common, can be fatal in 30% of cases. Clinical manifestations vary but can include chest pain, dyspnea, palpitations, heart failure symptoms, and arrhythmias. Diagnosis involves echocardiography, cardiac MRI, and endomyocardial biopsy. Treatment includes high-dose corticosteroids with potential additional immunosuppressants. Baseline EKG and troponin are recommended before ICI initiation, but routine surveillance is not advised. Subclinical myocarditis is a challenge, with unclear management implications. So let’s dive in and learn about cardiotoxicity of novel immunotherapies with Drs. Giselle Suero (series co-chair), Evelyn Song (episode FIT lead), Daniel Ambinder (CardioNerds co-founder), and Tomas Neilan (faculty expert). Audio editing by CardioNerds Academy Intern, Dr. Maryam Barkhordarian.

Pearls and Quotes – Cardiotoxicity of Novel Immunotherapies
Immune checkpoint inhibitors (ICI) play a crucial role in current oncology treatment by enhancing T-cell recognition against tumors.
ICI-related cardiac immune-related adverse events (iRAEs) include myocarditis, heart failure, stress-cardiomyopathy, conduction abnormalities, venous thrombosis, pericardial disease, vasculitis, and atherosclerotic-related events.
ICI myocarditis can be fatal; thus, prompt recognition and treatment is crucial.
Management includes cessation of the ICI and treatment with corticosteroids and potentially other immunosuppressants. Close monitoring and collaboration with cardiology and oncology are crucial.
Rechallenging patients with immunotherapies after developing an iRAE is controversial and requires careful consideration of risks and benefits, typically with the involvement of a multidisciplinary team.
Show notes – Cardiotoxicity of Novel Immunotherapies
What are immune checkpoint inhibitors (ICIs)?
ICIs are monoclonal antibodies used to enhance the body’s immune response against cancer cells. Currently, there are four main classes of FDA-approved ICIs: monoclonal antibodies blocking cytotoxic T lymphocyte antigen-4 (CTLA-4), programed cell death protein-1 (PD-1), lymphocyte-activation gene 3 (LAG3), and programmed cell death ligand-1 (PD-L1).
ICIs can lead to non-specific activation of the immune system, potentially causing off-target adverse events in various organs, including the heart, leading to myocarditis.
The mechanisms of cardiac iRAEs are not fully understood, but they are believed to involve T-cell activation against cardiac antigens, which leads to inflammation and tissue damage.
What are the cardiotoxicities related to ICI therapies?
ICI-related cardiac immune-related adverse events (iRAEs) include myocarditis, heart failure, stress-cardiomyopathy, conduction abnormalities, venous thrombosis, pericardial disease, vasculitis, and atherosclerotic-related events.
ICI-related myocarditis is considered rare compared to other systemic IRAEs. While the incidence rate of ICI-myocarditis is around 0.7-2.0%, it can be fatal in 30% of cases.
Clinical manifestations vary but can include chest pain, dyspnea, palpitations, heart failure symptoms, and arrhythmias. Severe cases of ICI myocarditis can present as cardiogenic shock or complete heart block (a fulminant myocarditis picture).
The timing of adverse events is typically within the first three months of starting immunotherapy, with the majority occurring early on; however, some cases may present after three months.
Increased clinical suspicion is key for early recognition and prompt diagnosis and treatment.
What is the general approach to the diagnosis of ICI-myocarditis?
Diagnosis is based on clinical history and presentation, elevated troponin, and imaging findings. Echocardiography (with global longitudinal strain) and cardiac MRI (with T1 and T2 mapping as per the modified Lake Louise Criteria) are key diagnostic tools. If cardiac MRI is not diagnostic but suspicion remains high, an endomyocardial biopsy is the next diagnostic step.
Baseline cardiac tests, such as ECG and troponin, are important before initiating ICIs in every patient to serve as a reference standard for comparison in case of troponin elevation during therapy. However, routine surveillance of asymptomatic patients on ICIs is not recommended.
How do endomyocardial biopsy findings for ICI-myocarditis compare to other types of autoimmune-mediated conditions such as transplant rejection?
ICI-myocarditis is pathologically almost identical to transplant rejection; therefore, a similar grading system used for transplant rejection is applied to ICI-myocarditis to determine the severity and provide guidance on the intensity of immunosuppression.
What are the treatment strategies for ICI-myocarditis?
In general, all patients with suspected ICI-myocarditis should have their immunotherapy held temporarily until the diagnosis is confirmed. Next, patients should be typically admitted to an inpatient unit with telemetry capabilities, given the risk of progression to complete heart block and cardiogenic shock.
High-dose corticosteroids are the first-line pharmacological treatment, but the optimal dose varies between guidelines. An approach for severe life-threatening cases based on the NCCN and SITC guideline recommendations is a pulse of high-dose corticosteroids (consider 1000 mg methylprednisolone IV daily for 3–5 days until troponin normalizes) followed by a taper of 1–2 mg/kg methylprednisolone or oral prednisone for 4–6 weeks.
For patients who do not respond to high-dose corticosteroids, additional immunosuppressive therapies can be considered, including intravenous immunoglobulin (IVIG), mycophenolate mofetil, anti-thymocyte globulin (ATG), alemtuzumab (monoclonal antibody to CD52), abatacept (CTLA-4 agonist), or plasmapheresis. This is an area where more data is needed to support guidelines for patient treatment. Currently, there are ongoing studies in this area, such as a phase 3 clinical of Abatacept for immune checkpoint inhibitor-associated myocarditis (ATRIUM, NCT053359280)
High doses of corticosteroids used to treat ICI-associated myocarditis may adversely impact cancer outcomes. Further research is needed to understand the impact of cardiac toxicities and immunosuppressive treatments on cancer outcomes
Can patients be re-treated after an episode of ICI myocarditis?
Patients who develop ICI-associated adverse events, including myocarditis, may have a second chance and be rechallenged with ICIs after resolution of the adverse event, but this decision should be made carefully considering the risks and benefits.

Pearls and Quotes – Cardiac Tumors
Keep it simple when approaching an intracardiac mass; start with transthoracic echocardiography (TTE) and use transesophageal echocardiography (TEE) or cardiac magnetic resonance (CMR) based on the clinical context. Use TEE when suspecting valvular vegetations or thrombi & CMR for intracavitary cardiac masses.
Cardiac tumors can manifest with a variety of symptoms; however, they are more commonly diagnosed as an incidental finding!
When faced with the dilemma of selecting the most suitable imaging modality for evaluating a cardiac mass, consider the following hierarchy: begin with TTE as the first choice, followed by CMR. If the patient cannot undergo CMR, the next step is cardiac computed tomography (CT) or Fluorodeoxyglucose F18 positron emission tomography (FDG-PET).
TEE is especially useful for the evaluation of small, highly mobile cardiac masses!
Imaging cannot substitute a tissue diagnosis of cardiac masses. However, in cases of advanced malignancy, it may not always be necessary.
Show notes – Cardiac Tumors
Segment One: A big “picture” Approach to Cardiac Tumors
Let’s start with an overview of cardiac masses
Neoplastic vs non-neoplastic
Neoplastic lesions can be further classified into Primary Cardiac Tumors (PCT’s) & Secondary Cardiac Tumor (SCT’s)
A majority of PCTs are benign (up to 90%!); however, rarely, they may be malignant.
SCTs are more common than PCTs, and, by definition, they are malignant tumors.
Now, let’s look at the tools you can use to aid with the diagnosis of cardiac masses…
Step 1: Investigate the cardiac mass initially with TTE.
Step 2: Collect clues through history-taking & examination.
If suspecting valvular vegetations (as in infective endocarditis!) or left atrial appendage thrombus, characterize the mass further with TEE.
Consider the possibility of metastatic cardiac tumors in patients with a known malignancy, as they are more common than primary cardiac tumors.
In cases where it is uncertain if the mass is a cardiac tumor or thrombus, use CMR to differentiate the two entities.
Some findings on TTE that support the presence of a thrombus include left ventricular dysfunction with segmental wall motion abnormalities and/or apical aneurysm as these result in local pockets of stasis (think: Virchow’s triad)
Step 3: Put it all together!
Think about whether a tissue biopsy will be needed. If yes, determine whether a negative margin or open biopsy will be required.
Segment Two: Symptoms, Symptoms, Symptoms!
Cardiac tumors may be symptomatic and present in the 3 key ways as outlined below (Think COD 🐟). However, they are more commonly identified as incidental findings!
Constitutional symptoms (fever, arthralgias, weight loss, malaise/fatigue)
Obstruction – Interfering with blood outflow, arrhythmias, interference with valves causing regurgitation, pericardial effusion +/- tamponade (presyncope, syncope, dyspnea, chest discomfort)
Distal embolization (pulmonary or systemic thromboembolic phenomenon)
When a metastatic tumor is present, distinguishing symptoms originating from the heart becomes challenging due to potential overlap with symptoms caused by the primary malignancy. This stands in contrast to cases of primary cardiac tumors like myxomas, where symptom localization to the heart is more straightforward.
Segment Three: Multimodality Imaging
Imaging modalityBest used forAdvantagesDisadvantagesTTEInitial diagnostic modality Masses arising from valvesGood spatial resolution Understanding of hemodynamic significance of massLack of tissue characterization Poor acoustic window in select casesTEESmall highly mobile valvular lesions (<1cm) Visualization of structures with greater accuracy compared to TTE Use of enhancing agents can help differentiate vascular tumors from non-vascular & thrombusLack of tissue characterizationCMRDifferentiates tumor from thrombus. Identifies non-tumor masses or “pseudo-masses,” e.g. cysts, lipomasTissue characterization w/ T1, T2 weighted imaging and gadolinium enhancementLower temporal resolution Limited availability Interference from implanted electrical devicesCT & FDG-PETDifferentiates benign from malignant tumorsAlternative to CMR in pts. w/ claustrophobia & older generation cardiac devicesCT with limited soft tissue & temporal resolution compared to CMR Dietary preparation before FDG
Segment Four: The Issue With Tissue!
Tissue diagnosis is essential for the diagnosis of primary cardiac tumors; however, it may be less important for metastatic tumors to the heart in cases of known advanced-stage malignancies such as melanoma, breast, and lung.
An overview of a rare primary cardiac malignancy: Carney Complex!
A complex hereditary syndrome that affects multiple organs, including the heart, skin & endocrine organs.
Epidemiology:
Autosomal dominant
Young age groups in both sexes
Clinical presentation
Intra-cardiac/extra-cardiac myxomas; intra-cardiac myxomas are multiple, bilateral (atrial and ventricular) & multicentric.
Skin findings commonly include lentigines and blue nevi.
Endocrine abnormalities include Cushing syndrome, pituitary & adrenal adenomas, thyroid dysfunction.
Diagnosis
Clues on CMR
SSFP (dteady-state free precession) cine imaging, an association of punctiform areas of high & low signal intensity consistent with “Blackberry appearance”
Hypoperfused enhancement pattern at first-pass perfusion imaging
High signal T2-imaging, iso-intense on T1-weighted imaging
Treatment
Surgical resection
Annual surveillance for Carney complex as they frequently recur (compared with surveillance every 3-5 years for non-Carney myxomas)
Genetic testing for PRKAR1 mutations in 1st degree family members
Segment Five: “Secondary” to None
Secondary cardiac tumors (SCT’s)
Epidemiology:
Cardiac metastasis is 20-40 times more common than primary cardiac tumors.
Etiology:
Routes of spread: hematogenous, lymphatic, transvenous, direct invasion
Most common malignancies to metastasize to heart include melanomas, carcinomas of breast, lung and esophageal.
Clinical Presentation
Pericardial effusion, tamponade
Arrhythmias – “resistant” to antiarrhythmic drugs
Heart failure due to myocardial infiltration
Valvular dysfunction due to intracavitary masses that impede blood flow.
Diagnosis
Echocardiography is the initial test of choice.
MRI
Most malignancies exhibit low signal on T1-weighted imaging & high signal intensity on T2-weighted imaging.
Exception, metastaticmelanoma, which appears hyperintense on T1-weighted imaging due to paramagnetic T1 shortening effects of melanin.
FDG-PET/CT
In cardiac metastasis, the myocardium has high metabolic activity and can mimic FDG uptake seen in a tumor.
Ensure adequate dietary preparation to suppress glucose uptake of normal healthy myocardium.
Multi-disciplinary approach to management
Tissue diagnosis is necessary.
Referral to an interventional cardiologist for transvenous biopsy, or
Referral to a cardiac surgeon for minimally invasive surgery
Note – tissue diagnosis can come from another metastatic site.
Pathologist to confirm the malignant nature of the tumor.
Cardio-oncologist to facilitate multidisciplinary team discussion involving oncologist and cardiac surgeon on the best approach to treatment.
Neoadjuvant chemotherapy or radiotherapy vs. cardiac surgery

November 26, 2023346. CardioOncology: Disparities in CardioOncology – Towards Health Equity with Dr. Javier Gomez-Valencia
CardioNerds co-founder Dr. Dan Ambinder, series chair Dr. Giselle Suero Abreu, and episode FIT Lead Dr. Rachel Ohman discuss disparities in cardiooncology with Dr. Javier Gomez Valencia, the Director of Cardio-Oncology services at John H. Stronger Jr. Hospital of Cook County. Dr. Rachel Ohman drafted show notes. Audio editing by student doctor Shivani Reddy.
A disproportionate burden of both cancer and cardiovascular disease affects racial and ethnic minority groups as well as lower-income communities. Similar patterns of vulnerability exist among cancer survivors with cardiovascular disease, although further investigation in these subpopulations is needed. We discuss a comprehensive approach to the cardio-oncology patient, our current understanding of the social and structural determinants of disparities in cardio-oncology populations, and other contributions to inequity in the field. Given the growing population of cancer survivors and limited accessibility to cardio-oncology specialists, these topics are of critical importance to anyone caring for cancer patients who have or are at risk for cardiovascular disease.

Pearls and Quotes – Disparities in CardioOncology
Social and structural determinants of health are drivers of cardiovascular and cancer disparities. Existing data on cardiotoxicity outcomes suggests these determinants also contribute to disparities in cardio-oncology.
Assessing social and structural determinants of health should be a routine part of evaluating a patient with an active or prior history of cancer.
Customs, country of origin, and immigration status matter. Differential risk profiles among Hispanic/Latinx sub-populations require further investigation.
Black patients, particularly black women with breast cancer, have elevated morbidity and mortality from cardiotoxicity. Data suggest contributions from social determinants of health.
Representation in clinical trials must be diversified for applicability to our diverse patient populations. Concerted efforts should be made to recruit diverse clinical trial participants and help patients from diverse communities effectively participate in the research process, contributing to the advancement of science.
Show notes – Disparities in CardioOncology
How do you approach the evaluation of a new patient in cardio-oncology? How do social and structural determinants of health impact treatment-associated cardiotoxicity?
The evaluation of a new patient should include an assessment of a patient’s intrinsic risk factors, risks associated with cancer treatment, and consideration of cardioprotective therapeutic strategies
Social and structural vulnerabilities should also be assessed routinely as a part of risk stratification. Providers should take stock of a patient’s demographic (e.g., race/ethnicity, gender), socioeconomic (e.g., occupation, insurance status, food security, housing security), environmental (e.g., transportation, proximity to health resources, neighborhood safety), and sociocultural (e.g., psychosocial stressors, discrimination, acculturation) determinants that are in turn modulated by larger systemic forces like structural racism.
This comprehensive risk assessment can guide the strategies to mitigate cardiovascular risk before, during, and after cancer treatment.
What barriers to cardio-oncology care are unique to the Hispanic/Latinx population?
The Hispanic/Latinx population now comprises 19% of the US population. A disproportionate fraction of the Hispanic/Latinx population is uninsured (about 20%).
In addition to insurance barriers, some members of this population can face difficulties from language barriers and limited access to preventative care.
Existing data suggest differential risk profiles for sub-populations of Hispanic/Latinx patients based on country of origin, customs, and immigration status. Further research is needed to investigate disparities among different sub-populations.
What disparities are faced by Black patients with cancer?
Black patients have an elevated risk of morbidity and mortality from cancer and are more likely to develop cardiotoxicity than their White counterparts. Black patients with breast cancer who receive anthracycline or HER2-directed therapy have a two- to three-fold risk of cardiotoxicity when compared to their White counterparts.
Black patients with HER2+ breast cancer treated with trastuzumab are more likely to develop LV dysfunction than White counterparts, even after controlling for age, disease state, and cardiovascular risk factors. This suggests a role for social determinants of health that have yet to be elucidated.
How can patients’ sexual orientation and gender identity influence disparities in cardio-oncology, particularly for LGBTQIA+ patients?
Some of the barriers this population faces are related to social stigmatization as well as structural discrimination (e.g., lack of providers with appropriate expertise).
Difficulties with accessing trusted providers can impair patients’ ability to have longitudinal care and optimal cardiotoxicity surveillance.
What other areas of cardio-oncology might contribute to ongoing outcomes disparities, and how should we approach those disparities?
Underrepresentation of minority groups in clinical trials is an ongoing issue. It results in our extrapolating data from homogenous populations and applying it to more diverse populations not represented adequately.
Clinical trial enrollment requires more diverse and inclusive recruitment and visibility. However, we also should help patients and communities feel included in the research process, particularly given historical examples of medical exploitation.
The landscape of cardiology providers also requires diversification. A diverse workforce benefits patients as well as providers.
Cardiologists and healthcare providers also need to engage in political advocacy to help advocate for underrepresented vulnerable groups to combat socioeconomic disparities and public health crises that create barriers to optimal care.

Pearls and Quotes – Arrhythmias in CardioOncology
Arrhythmias are common in cancer patients due to shared risk factors and bi-directional risk between cardiac and oncologic disorders. Many cancer therapeutics can be directly arrhythmogenic or lead to cardiotoxicities that pre-dispose to arrhythmias.
Though incidence of arrhythmia can be significant increased with some cancer therapeutics (e.g. ibrutinib), there is not specific data to support proactive ambulatory monitoring for arrhythmia without evidence of clear symptoms.
Atrial fibrillation is the most common arrhythmia in cancer patients and management of atrial fibrillation, as well as other tachyarrhythmias, is unchanged from management in non-cancer patients. General principles of when to start anticoagulation or rate vs rhythm control are not significantly different (e.g. still use CHA2DS2-VAsC, monitor for symptoms etc), but providers should be more mindful of drug-drug interactions with cancer therapeutics.
Cancer therapeutics as well as common medications used to treat side effects or complications (e.g. antiemetics, antibiotics, etc) can prolong the QT interval and increase risk of Torsades de pointes (TdP). The QTc should be monitored with an ECG for patients on these medications. If a patient does develop a serious arrhythmia like TdP, management is similar to that in non-cancer patients.
The goal of arrhythmia management in cardio-oncology is to prevent cardiovascular disease from becoming a barrier to appropriate cancer therapy. Though cancer therapeutics should be temporarily or permanently discontinued in potentially fatal events (e.g TdP from QTc prolonging meds), the overall goal is to manage the arrhythmias appropriately to allow cancer therapeutics to be continued or restarted.
Show notes – Arrhythmias in CardioOncology
What is the prevalence of arrhythmias in patients with cancer?
Arrhythmias are common in patients with cancer due to a multitude of factors. Atrial fibrillation is the most common arrhythmia in this population and occurs in approximately 5% of patients with cancer. The driving forces are multifactorial and include the direct arrhythmogenic effects of cancer therapeutics and cardiotoxicities of cancer therapeutics that make arrhythmogenesis more likely. Additionally, there is a bi-directional link between cancer and cardiac disorders. For example, not only is atrial fibrillation more common in patients with cancer, but there is also a higher incidence of cancer in patients with atrial fibrillation, likely due to shared risk factors. Risk factors in patients with cancer that make arrhythmias more likely include advanced age, metabolic disturbances, electrolyte abnormalities, and elevated levels of inflammation and catecholamines.
(How) Do cancer therapeutics increase the risk of arrhythmias?
Many cancer therapies are either directly or indirectly arrhythmogenic. Though therapies like the BTK inhibitor ibrutinib have a direct link to an increase incidence of atrial fibrillation, other medications like immune checkpoint inhibitors can cause myocarditis, reduce cardiac function, and predispose to arrhythmias. The following table includes broad categories of cancer therapeutics that are linked to arrhythmia:
What is the appropriate arrhythmia monitoring strategy for patients receiving cancer therapy?
Though there is a clear increased risk of arrhythmia in many patients with cancer receiving specific therapeutics, there is not specific data to support proactive monitoring in these patients. One meta-analysis showed that when compared to alternative regimens, ibrutinib increased the risk of incident AF compared to alternative therapies (RR 3.9, 95% CI 2.0-7.5, P <0.0001), with overall AF incidence of 3.3 per 100 person-years compared to 0.84 per 100 person-years in the ibrutinib and non-ibrutinib groups, respectively. Though proactive monitoring might lead to more or earlier detection of AF in this population, there is a lack of data to support improved outcomes with monitoring asymptomatic patients. Additionally, the clinical relevance of subclinical and/or short episodes of atrial fibrillation remains uncertain. Because of this, there are no current recommendations for broad proactive monitoring, though monitoring should be considered in patients with signs or symptoms that could be consistent with arrhythmia.
What is the management of arrhythmias in patients with cancer?
Management of arrhythmias in patients with cancer is similar to general management in non-cancer patients. For AF, a rhythm control strategy is preferred for patients with paroxysmal AF and in patients who are symptomatic. For other patients who are asymptomatic, a rate control strategy is reasonable. One notable exception is when control of the AF becomes a barrier to the oncology team. In these situations, more aggressive rhythm control is preferred to facility oncologic care. Anticoagulation is also approached in a similar way to non-cancer patients. Patients with a CHA2DS2-VAsC score >2 for men and >3 for women warrant anticoagulation. Many patients with cancer are anemic, thrombocytopenic, or prone to bleeding, which should also be taken into account when prescribing anticoagulation. Left atrial appendage closure may be a consideration for select patients.
As for medications that cause QT prolongation, malignant arrhythmias are quite rare and mostly occur in patients with QTc > 500 ms. This can be multifactorial as many patients with cancer may have episodic metabolic or electrolyte abnormalities in addition to cancer therapeutics or symptom/complication management medications (e.g. antiemetics, antibiotics, etc) which can prolong the QTc or lower the threshold for arrhythmogenesis. Life threatening arrhythmias like Torsades de pointes (TdP) are treated similar to that in non-cancer patients, which can include magnesium, increasing HR with isoproterenol or transvenous pacing, anti-arrhythmic drugs, or cardioversion in addition to addressing the underlying cause.
Balancing arrhythmia risk with cancer therapeutics
An important goal in cardio-oncology is to prevent cardiovascular disease from becoming a barrier for a patient to receive appropriate cancer therapy. The goal is to facilitate the treatment plan that the oncologist thinks is optimal for their cancer, not to protect the heart at the expense of appropriate oncologic care. This is a difficult balancing act and, in the case of serious or potentially fatal events (e.g. Torsades from QTc prolonging meds, vasospasm with ischemia from 5FU, severe myocarditis from immune checkpoint inhibitors etc.), it is often necessary to discontinue the cancer therapeutic temporarily or permanently. Ideally, the arrhythmia should be treated and controlled allowing the patient to continue therapy while minimizing the cardiac symptoms and side effects.

Pearls and Quotes – Thromboembolic Disease in Cardio-oncology
Patients with cancer are at higher risk of developing both arterial and venous thromboembolic events compared to the general population.
Certain cancer subtypes are associated with a relatively higher risk of developing thromboembolic complications.
Anticoagulation type and duration should be dependent on patient characteristics and risk factors, with shared decision-making between the patient and their providers.
Subgroups of patients may benefit from more aggressive management of their atherosclerotic cardiovascular risk factors while being treated for cancer to reduce the risk of thromboembolic complications.
Show notes – Thromboembolic Disease in Cardio-oncology
What are the incidence and main manifestations of thromboembolic events (venous and arterial) in patients with active malignancy?
Approximately 10% of outpatients with active cancer have venous thromboembolic events, many of which are asymptomatic. Clinically relevant VTEs are predominantly deep venous thrombosis (DVTs) with pain and/or swelling of the involved extremities or pulmonary emboli (PEs) resulting in chest pain and/or shortness of breath. VTE is the number one preventable cause of death for all hospitalized patients, and the ability to prevent and treat these events is crucial, particularly in high-risk populations such as patients with cancer.
Are there any high-risk associations with specific cancer subtypes?
Patients with metastatic disease and those receiving chemotherapy are more likely to develop arterial or venous thromboembolic events. Patients with acute myelogenous leukemia (AML) and thrombocytopenic patients are at the lowest risk for thromboembolic events. Multiple myeloma patients on medication such as proteasome inhibitors or lenalidomide appear at particular risk. Patients with localized, early-stage cancers such as breast, prostate, and melanoma are also at lower risk.
What are the main risk factors to identify patients at a higher risk of developing thrombotic complications?
Patients with a sedentary lifestyle, deconditioning, and undergoing active treatment with chemotherapy are at the highest risk of developing DVT or PE.
How should we approach choosing the optimal type and duration of anticoagulation for acute pulmonary embolism (PE) in the setting of malignancy?
This remains an area of active research. Historically, patients would receive systemic anticoagulation with heparin followed by warfarin. Low molecular weight heparin (LMWH) has been found to be superior to warfarin in this patient population. In the recent trials comparing LMWH to direct oral anticoagulants (DOACs), particularly apixaban, edoxaban, and rivaroxaban, a similar incidence of VTEs and relatively equivalent bleeding events have been found. This has transitioned the field towards the higher use of DOACs, except for gastric cancers, in which DOACs have been found to have higher bleeding risk. Dabigatran has been found to be associated with a higher incidence of bleeding and gastrointestinal side effects compared to other DOACs. Important considerations for the use of DOACs are the patient’s renal function and the ability to take oral medications or issues with gastrointestinal absorption.
For acute PE, three months of treatment is the minimum for the standard of care. For patients with ongoing treatment with systemic chemotherapy or radiation, treatment for at least six months may be considered, or even indefinitely, if risk factors for recurrence persist. Shared decision-making with patients regarding the relevant risks and benefits of ongoing anticoagulation remains critical.
What are some risk assessment models to help identify patients at high risk for developing recurrent thrombotic events?
The Khorana score, which includes prechemotherapy platelet count ≥350 x109/L, elevated WBC >11 x109/L, low hemoglobin <10g/dL, or BMI ≥35 kg/m2 may help risk-stratify higher-risk patients. Certain types of cancers place patients at different risks; for example, gastric and pancreatic cancers confers higher risk, while patients with lung cancers, lymphoma, or genitourinary cancers confer a mildly elevated risk.
Patients with no risk factors have less than <1% risk of PE or DVT in the following 2.5 months, those with 1 or 2 points have about 2% risk of PE or DVT in the following 2.5 months, and those with >3 points have about 7% risk of PE or DVT in the following 2.5 months.
How does one manage recurrent thrombotic events, particularly while patients are already on an oral anticoagulant?
One major consideration in patients with recurrent thrombotic events is ensuring adherence, as there may be concerns with patient education, access, or cost which need to be addressed. Once compliance is confirmed, a patient can be switched from one DOAC to another DOAC or from one DOAC to LWMH, with the twice-daily dose having the strongest evidence for efficacy.
Rarely, concurrent treatment with antiplatelet therapy and LWMH may be considered in patients at very high risk for recurrent thrombotic events, particularly in patients with widely disseminated cancers with vascular complications. Notably, workup for underlying hypercoagulability should be considered in patients with localized malignancies with recurrent thromboembolic events.
What are considerations for scenarios with high bleeding risk when there is a strong indication for anticoagulation?
For patients with chemotherapy-induced thrombocytopenia, thromboelastography (“TEG” scan) may be valuable in guiding whether patients are hyper- or hypo-coagulable. Patients with platelet count <20K should generally not be on anticoagulation. For patients anticipated to have thrombocytopenia sustained through treatment, discussion with the treating oncology team may guide towards withholding ongoing anticoagulation. Mobility and sequential compression devices (SCDs) should be advised for patients to avoid the development of DVTs while patients are in the hospital. As platelet counts rise, consideration of subtherapeutic doses of heparin may be considered.
Any lesion with metastasis to the brain is at risk for bleeding. Discussion with oncology, neuro-oncology, and neurosurgery is crucial in identifying the risk of hemorrhage of these lesions. Primary brain tumors, such as glioblastoma, are associated with an elevated risk of DVT, likely attributable in part to reduced mobility and VEGF-targeted treatment.
Management of malignant pericardial effusions varies by etiology. Patients with local malignant pericardial effusion may be managed with pericardiocentesis with catheter drainage versus pericardial window, depending on clinician availability and expertise.
What is the role of inferior vena cava (IVC) filters in the management of patients at high risk for developing thromboembolic events?
For patients with active DVT and PE burden with active or very high risk for bleeding, it may be considered to place a retrievable IVC filter with the goal of removal within 4-6 weeks, and anticoagulation restarted as soon as possible. Of note, IVC filters that remain in place for longer periods of time place the risk of the development of thrombi and distal embolization.
How does the management of arterial thrombotic events for patients with active malignancy differ from the treatment of venous thromboembolic disease?
Arterial thrombotic events may be sequelae of atherosclerotic cardiovascular disease, dysfunction of the coagulation cascade, or both. Patients with atherosclerotic cardiovascular disease are at higher risk for developing cardiovascular events when treated for cancer. Certain patients, such as men with prostate cancer, appear to be at higher risk related to hormonal derangements during treatment. Proactive management of atherosclerotic risk factors in these patients is imperative with modalities such as coronary computed tomography (CT) scans to identify the burden of atherosclerotic coronary disease with coronary calcium scoring. These patients may benefit from more aggressive treatment with statin therapy and antiplatelet therapy. Patients with preexisting coronary disease being treated with endocrine therapies or VEGF tyrosine kinase inhibitors (TKIs) may be at higher risk for atherosclerotic cardiovascular events during treatment and, therefore indicated for more aggressive lifestyle and risk factor modification.

Pearls and Quotes – Interventional CardioOncology
Cancer should be treated as a chronic illness akin to hypertension or diabetes and should not deprive patients from receiving appropriate cardiovascular treatment if otherwise indicated (e.g., PCI for acute coronary syndromes, etc.).
In cancer patients with stable angina, along with maximizing medical therapy, multimodality imaging (CTA/PET), intravascular imaging (IVUS/OCT), and physiologic testing (iFR/FFR) should be used routinely to prevent unnecessary stenting.
Caution is required in the cath lab for the cancer patient with thrombocytopenia. Techniques include utilizing micropuncture access, transfusing appropriate blood products based on thromboelastogram (TEG), and adjusting antiplatelet therapy regimens and duration.
Transcatheter aortic valve replacement (TAVR) is now the recommended treatment for most cancer patients with symptomatic/severe aortic stenosis and, if otherwise indicated, should preferably be pursued prior to cancer treatment to optimize the patient’s cardiovascular fitness and tolerance of anti-cancer therapy.
Pericardiocentesis in the cancer patient should be performed preferably under fluoroscopy with echocardiography and vascular ultrasound guidance (“triple guidance”).
Show notes – Interventional CardioOncology
What is the general approach to cardiovascular illness in the cancer patient?
Cancer and cardiovascular diseases share numerous risk factors. In addition, cancer and cancer therapies can be atherogenic, by means of inducing pro-inflammatory and hyprecoagulable states, increasing the risk of ischemic heart disease, stroke, and peripheral arterial disease.1
In the outpatient setting, emphasis should be placed on optimizing cardiovascular risk factors and improving overall cardiovascular fitness by exercising, having a healthy diet, and having regular sleep hours as these favor survivorship after cancer treatment. Questions to be answered in the clinic are – Is the patient cardiovascularly fit? Will the patient’s heart withstand cancer treatment? Is there concern for coronary artery disease, valvular disease, pericardial disease, or pulmonary hypertension?
Risk assessment and treatment for cancer patients with suspected or known cardiovascular disease should generally follow established ACC/AHA guidelines, with special considerations as outlined by the Society of Cardiovacular Angiography and Interventions (SCAI).2
Pre-chemotherapy cardioprotection for patients without coronary artery disease (CAD) with prophylactic beta-blockers, ACEi/ARB, and statins should be considered when appropriate. For high-risk patients with CAD, blood pressure control, frequent screening via echocardiography, and measurement of serum cardiac biomarkers is encouraged.
What is the approach to stable angina in cancer patients?
Start the evaluation by identifying cardiovascular risk factors and cardiovascular co-morbidities such as hypertension and diabetes. Review prior or active cancer treatments that might increase the risk for CAD (e.g., chest radiotherapy).
Utilize prior imaging that the patient may have had for cancer staging, to look for coronary artery calcification.
Depending on the patient’s risk profile for ischemic heart disease, stress testing/multi-modality imaging techniques ranging from coronary CTA to cardiac PET can be pursued to delineate coronary anatomy and identify the myocardium at risk.
The final step is invasive coronary imaging – with the intent of fixing main vessel, proximal, and ostial lesions. A wait and watch approach with optimized medical management is preferred for stable lesions in small branches subtending smaller portions of the myocardium.
Intravascular imaging (optical coherence tomography – OCT, intravascular ultrasound – IVUS) and physiologic techniques (iFR and FFR) add value to guide decision-making about revascularization.
Maximally optimize medical therapy before resorting to an invasive strategy.
Sometimes, in anticipation of progressing CAD following cancer treatment/cancer evolution, it may be pertinent to have an aggressive approach during the initial presentation of the patient in the clinic. Patients with advanced cancer may have anemia, thrombocytopenia, or pancytopenia which could make downstream coronary interventions more complicated.
What is the approach to acute coronary syndromes (ACS) in cancer patients?
Cancer patients with ACS typically present with dyspnea, followed inconsistently by chest pain thereby creating a layer of challenge in the diagnosis. A high index of suspicion is necessary in order to not miss this diagnosis. A subset of patients with ACS-type presentation could have stress induced cardiomyopathy or chemotherapy induced vasospasm/endothelial dysfunction (5-fluorouracil is the most common cause).
After risk assessment, invasive approach with left heart catheterization/coronary angiogram with or without intervention can be the next best step in selected patients.
Choosing the appropriate stent (bare metal stent, BMS, vs. drug eluting stent, DES) and antiplatelet regimen is key, especially in the setting of chronic thrombocytopenia.3 Although BMS were once commonly used in cancer patients due to their brief antiplatelet drug requirement, they are associated with increased risks for in-stent restenosis and are not preferred in the current era. Modern DES have safer profiles and evidence shows that abbreviated dual antiplatelet thearpy (DAPT) regimens can be implemented with DES as well, if needed.
In cancer patients, due to various factors such as thrombocytopenia or need for cancer treatment resumption, DAPT duration may be abbreviated to <6 months, and recent studies have shown the risk of stent thrombosis to be minimal.5,6 As in non-cancer patients, stent optimization with intravascular imaging (IVUS or OCT) is good practice.4
Hematologic malignancies have the highest risk of thrombocytopenia (less than 10,000) and may necessitate even more abbreviated courses of DAPT, after a discussion of the risks with the patients. A multi-disciplinary team comprising the cardiologist, interventional cardiologist, and the hematologist (the cardio-oncology team) should be involved in decision making.
Balloon angioplasty without stenting should be considered for cancer patients who are not candidates for DAPT (i.e., platelets <30.000/mL) or when a non-cardiac procedure or surgery is necessary as soon as possible. The risk of a complication (i.e., iatrogenic coronary dissection) requiring stenting should be discussed and contingencies should be in place.
Cancer treatment resumption following percutaneous intervention (PCI) depends on the malignancy being treated. In acute hematological malignancies treatment can be started/resumed within days after PCI, however in slow growing tumors treatment can be started/resumed in 2-4 weeks. Radiation therapy can be resumed as soon as needed. Surgery could be performed after at least 1 month of DAPT therapy.
What are special considerations prior to invasive testing and therapies in cancer patients with thrombocytopenia?
Approximately 10% of cancer patients have concurrent thrombocytopenia and thrombosis.
In a thrombocytopenic patient with ACS requiring PCI, a thorough risk/benefit discussion needs to occur, given the increased risk of bleeding.
Thromboelastograms (TEG) may be utilized to help choose the right product for transfusion among platelets, plasma, or cryoprecipitate. In the event of a catastrophic bleed, achieving hemostasis is paramount, and transfusion all three products may be considered rather than waiting for TEG scan.
Prophylactic platelet transfusion is recommended if the platelet count is <20,000/mL and one of the following: (a) high fever, (b) leukocytosis, (c) rapid fall in platelet count, (d) other coagulation abnormality, platelet count <20,000/mL in solid tumor patients receiving therapy for bladder, gynecologic, or colorectal tumors, melanoma, or necrotic tumors. Repeat platelet counts must be obtained after transfusion.
30–50 U/kg unfractionated heparin is the initial recommended dose for thrombocytopenic patients undergoing PCI who have platelets <50,000/mL. Activated clotting time should be maintained over 250 sec.
For platelet counts <30,000/mL, revascularization and DAPT should be decided after a preliminary multidisciplinary evaluation (interventional cardiology/oncology/hematology)
Aspirin administration may be used when platelet counts are >10,000/mL. DAPT with clopidogrel may be used when platelet counts 30,000–50,000/mL. Prasugrel, ticagrelor, and IIB-IIIA inhibitors should not be used in patients with platelet counts <50,000.
If platelet counts are <50,000, the duration of DAPT may be restricted to 2 weeks following PTCA alone, four weeks after bare-metal stent (BMS), and six months after second or third-generation drug-eluting stents (DES) if optimal stent expansion was confirmed by IVUS or OCT. There is data for shorter DAPT durations following newer DES platforms.
There is no minimum platelet count to perform a diagnostic coronary angiogram.
Radial access is preferred to femoral due to lower bleeding risk and increased patient satisfaction. Femoral access is the preferred approach for cancer patients on hemodialysis, those with abnormal Allen’s tests in both arms, multiple radial procedures or a-lines, bilateral mastectomy, or when a complex intervention is anticipated. Notably, radial access requires intravenous heparin administration to maintain vessel patency, for which thrombocytopenia may be a barrier.
What is the approach to valvular heart disease (aortic stenosis) in cancer patients?
In patients with cancer, there is a reduction in mortality when aortic stenosis is treated prior to cancer treatment.
Options include the percutaneous vs. surgical valve, although TAVR is now preferred for patients in all risk categories.7
Cancer treatment can generally be resumed two weeks after a percutaneous valve and two months after surgical valve replacement, although shorter waits may be necessary if cancer treatment is more urgent.
What is the approach to pericardiocentesis in cancer patients?
Malignant pericardial effusions are commonly encountered in cancer patients.
Percutaneous pericardiocentesis is preferred when indicated, as mortality/morbidity is high with a surgical approach.8
The procedure is preferably performed under fluoroscopy with echocardiography and vascular ultrasound guidance (“triple guidance”).
Obtain a chest x-ray to rule out colonic distension/gastric bubble. CT chest/abdomen is helpful for delineating landmarks.
A thorough physical exam of the patient, focusing on the scars (surgical/radiation), and cancers on the chest wall, should be performed.
For patients on blood thinners and chronic thrombocytopenia, an apical approach (lateral) is preferred to avoid puncturing the liver.
Micropuncture needle and small 5F sheath are utilized for access, inserted above the specific rib margin, to avoid the vascular bundles.
The pericardial drain should be maintained for a minimum of 3 days (optimally 5 days).

Pearls and Quotes – Cardio-Oncology: Training and Future Directions
It may be possible to achieve “COCATS level 2” cardio-oncology training during general cardiology fellowship. A dedicated cardio-oncology year may appeal to trainees who want to achieve “COCATS level 3”, i.e., dedicate their practice to caring for patients with complex cardio-oncology needs, become involved in clinical trials, and lead cardio-oncology clinical and training programs.
Supplemental learning opportunities for general fellows can include:
Rotating in a cardio-oncology clinic, ideally attached to a National Cancer Institute-designated cancer center
Multi-modality cardiac imaging
Participating in cardio-oncology research
Some currently available educational opportunities include:
The International Cardio-Oncology Society (ICOS) weekly webinars
The American Society of Echocardiography (ASE) webinars on global longitudinal strain
The American Society of Nuclear Cardiology lecture series on cardiac amyloidosis
Cardio-oncology focused conferences, such as the American College of Cardiology’s (ACC) Advancing the Cardiovascular Care of the Oncology Patient and Memorial Sloan Kettering’s Cardio-Oncology Symposium.
Each institution may have different inpatient cardio-oncology needs depending on whether there is a stand-alone cancer hospital or another format. Examples of inpatient consults that may benefit from having a cardio-oncologist involved include:
Cardiovascular risk assessment prior to bone marrow transplant or cancer related surgery in a patient with known coronary artery disease
Immune checkpoint inhibitor myocarditis
Chemotherapy-related cardiac dysfunction
Management of systemic anticoagulation in a patient with high CHA2DS2-VASc and chemotherapy related thrombocytopenia.
Show notes – Cardio-Oncology: Training and Future Directions
The need for cardio-oncology experience is undeniable given the growing population of patients with cancer and cardiovascular disease, particularly given the number of anti-neoplastic therapies with potential cardiovascular side effects. There are several strategies for incorporating cardio-oncology experiences into general cardiology training. These may include rotating through a cardio-oncology clinic, enhanced exposure to multimodality cardiac imaging including global longitudinal strain and participating in cardio-oncology research.
The need for dedicated formal training in cardio-oncology is more nuanced. If the goals of a formal fellowship align with a trainee’s career goals, an additional year of training can provide advanced exposure to complex medical decision-making, cardio-oncology specific imaging training (i.e., global longitudinal strain, MRI, PET), and even inpatient cardio-oncology experience at several centers. Prospective cardio-oncology trainees should gain clinical exposure during general cardiology fellowship and research exposure where available, and these experiences can factor into their decision to pursue a cardio-oncology fellowship.
Additional resources from national societies (e.g., ICOS, ACC, ASE) for cardio-oncology education can be made available to general cardiology trainees to expand their knowledge base. In some institutions, inpatient cardio-oncology consults may be appropriate. As a general rule, consultations regarding chemo- or immunotherapy-related cardiotoxicities or pre-stem cell transplant risk stratification may benefit from involvement of cardio-oncology in some form.
The future of cardio-oncology is bright, especially with the development of programs to train the next generation of cardio-oncologists!

July 12, 2023315. Case Report: A Mystery Mass in the Heart – University of Chicago – Northshore University
In this episode, CardioNerds co-founder Amit Goyal joins Dr. Iva Minga, Dr. Kevin Lee, and Dr. Juan Pablo Salazar Adum from the University of Chicago – Northshore in Evanston, IL to discuss a case of primary cardiac diffuse large B-cell lymphoma. The ECPR for this episode is provided by Dr. Amit Pursnani (Advanced Cardiac Imaging, Fellowship program director, NorthShore University HealthSystem). Audio editing by CardioNerds Academy Intern, Dr. Akiva Rosenzveig.
Case synopsis: A 77-year-old man with no significant medical history presents to the emergency department with progressive shortness of breath for 1 week. He reports an unintentional 15-pound weight loss in the prior month as well as constipation and abdominal/flank pain. On examination he was found to be tachycardic with a regular rhythm and further evaluation with a chest X-ray and chest CT scan demonstrated a large pericardial effusion. This was further investigated with an urgent echocardiogram that revealed a large pericardial effusion with a large mass attached to the pericardial side of the RV free wall, as well as signs of early cardiac tamponade. A pericardiocentesis was performed and 550mL of bloody fluid was withdrawn. The fluid was sent for laboratory analysis and cytology. A cardiac MRI demonstrated a large invasive mass in the pericardium and RV wall consistent with cardiac lymphoma. Cytology confirmed diffuse large B-cell lymphoma. Subsequent CT and PET scans did not find any other site of malignancy, giving the patient a diagnosis of primary cardiac diffuse large B-cell lymphoma. The patient underwent R-CHOP chemotherapy and was followed closely with repeat cardiac MRI and PET scans which demonstrated resolution of the cardiac mass at his one-year surveillance follow-up.
This case was published in US Cardiology Review, the official journal of CardioNerds. To learn more, access the case report article here.

Pearls – A Mystery Mass in the Heart – Cardiac Lymphoma
The most common cause of malignant cardiac masses is metastasis.
Primary cardiac tumors are rare.
Cardiac tumors are separated into 2 categories: benign and malignant. They are often differentiated based on their location and their degree of tissue invasion.
Multimodality imaging is essential in the diagnosis, management, and surveillance of cardiac masses.
A multidisciplinary team approach is invaluable for management of patients with cardiac tumors.
Show Notes – A Mystery Mass in the Heart – Cardiac Lymphoma
1. What is the clinical presentation of cardiac masses?
Cardiac masses can have a variable presentation. They can present with arrhythmias, angina, heart failure symptoms, or pericardial effusion. Patients can also be asymptomatic; the masses can be found incidentally on cardiac or chest imagining.
2. What is the differential diagnosis for cardiac masses?
Cardiac masses are separated into benign and malignant. The most common malignant cardiac masses are metastases from a distant source. The location of the mass is important in narrowing the differential.
3. What imaging modalities are used to diagnose cardiac masses?
Multimodality imaging is needed to describe the mass in detail and guide diagnosis. An echocardiogram is usually the first imaging modality. Cardiac MRI is a great modality that allows for the detailed visualization as well as tissue characterization of the mass. Cardiac CT, chest CT, and PET scans are also imagining modalities that can be used in the management of the mass.
4. How do you manage cardiac masses?
Management of cardiac masses depends on etiology (benign or malignant) and the associated hemodynamic changes associated with it. For example, if a benign cardiac mass is associated with significant valvular regurgitation, cardiac surgery needs to be considered for management. A multidisciplinary team including cardiology, heart failure, critical care cardiology, cardio-oncology, oncology, cardiac surgery, and other specialties may be involved in the management of cardiac masses and their manifestations.
