CardioNerds Co-Founder, Dr. Amit Goyal, along with Series Co-Chairs, Dr. Yoav Karpenshif and Dr. Eunice Dugan, and episode Lead, Dr. Sean Dikdan, had the opportunity to expand their knowledge on the topic of ventricular tachycardia and electrical storm from esteemed faculty expert, Dr. Janice Chyou. Audio editing by CardioNerds Academy Intern, Dr. Maryam Barkhordarian.



Electrical storm (ES) is a life-threatening arrhythmia syndrome. It is characterized by frequently occurring bouts of unstable cardiac arrythmias. It typically occurs in patients with susceptible substrate, either myocardial scar or a genetic predisposition. The adrenergic input of the sympathetic nervous system can perpetuate arrythmia. In the acute setting, identifying reversible triggers, such as ischemia, electrolyte imbalances, and heart failure, is important. Treatment is complex and varies based on previous treatments received and the presence of intra-cardiac devices. Many options are available to treat ES, including medications, intubation and sedation, procedures and surgeries targeting the autonomic nervous system, and catheter ablation to modulate the myocardial substrate. A multidisciplinary team of cardiologists, intensivists, electrophysiologists, surgeons, and more are necessary to manage this complex disease.



The CardioNerds Cardiac Critical Care Series is a multi-institutional collaboration made possible by contributions of stellar fellow leads and expert faculty from several programs, led by series co-chairs, Dr. Mark Belkin, Dr. Eunice Dugan, Dr. Karan Desai, and Dr. Yoav Karpenshif.

CardioNerds Dr. Josh Saef and Dr. Tommy Das join Dr. Omkar Betageri, Dr. Andrew Geissler, Dr. Philip Lacombe, and Dr. Cashel O’Brien from the Maine Medical Center in Portland, Maine to enjoy an afternoon by the famous Portland headlight. They discuss a case of a patient who presents with obstructive cardiogenic shock. Dr. Bram Geller and Dr. Jon Donnelly provide the Expert CardioNerd Perspectives & Review segment for this episode. Dr. Maxwell Afari, the Maine Medical Center cardiology fellowship program director highlights the fellowship program. Audio editing by CardioNerds Academy Intern, student doctor Tina Reddy.



This is the case of a 42 year-old woman born with complicated Tetralogy of Fallot repair culminating in a 29mm Edwards Sapiens (ES) S3 valve placement within a pulmonary homograft for graft failure who was admitted to the cardiac ICU for progressive cardiogenic shock requiring vasopressors and inotropic support. Initial workup showed lactic acidosis, acute kidney injury, elevated NT-proBNP, and negative blood cultures. TTE showed at least moderate biventricular systolic dysfunction. She was placed on furosemide infusion, blood cultures were drawn and empiric antibiotics initiated. Right heart catheterization demonstrated elevated right sided filling pressures, blunted PA pressures with low PCWP, low cardiac index, and low pulmonary artery pulsatility index. Intracardiac echocardiography (ICE) showed a large mass within the ES valve apparatus causing restrictive valve motion with a low gradient across the pulmonic valve in the setting of poor RV function. Angiography revealed a large filling defect and balloon valvuloplasty was performed with immediate hemodynamic improvement. Blood cultures remained negative, she was gradually weaned off of inotropic and vasopressor support, and discharged. Despite empiric treatment for culture negative endocarditis and ongoing anticoagulation, she was readmitted for recurrent shock one month later at which time the pulmonic mass was revisualized on ICE. A valve-in-valve transcatheter pulmonary valve (29mm ES S3) was placed to compress what was likely pannus, with an excellent hemodynamic result and no visible mass on ICE.

371. Case Report: The Curious Case of Obstructive Cardiogenic Shock – Maine Medical Center


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,

370. CardioOncology: Advanced Heart Failure in CardioOncology with Dr. Richard Cheng


CardioNerds, Dr. Richard Ferraro and Dr. Dan ambinder join Dr. Li Pang, Dr. Emily Hendricks, and Dr. Bei Jiang from West Virginia University to discuss the following case that features apical obliteration with biventricular thrombus. Dr. Christopher Bianco provides the Expert CardioNerd Perspectives & Review (E-CPR) for this episode. Audio editing by CardioNerds Academy Intern, student doctor Tina Reddy.



A 37-year-old Caucasian man with a history of tobacco smoking and hypertension who presented with chest pain and elevated troponin was admitted for non-ST elevation myocardial infarction (NSTEMI). Ischemic evaluation with an invasive coronary angiogram was negative. He was treated as NSTEMI and scheduled for outpatient cardiac MRI (CMR). The patient came back 2 months later with right arm weakness and confusion and was found to have an embolic stroke. Labs showed positive troponin with a flat trend and hypereosinophilia. Transthoracic echocardiogram (TTE) showed obliteration of LV and RV apex with thrombus and reduced LV systolic function. CMR was consistent with myocarditis with biventricular thrombus. The patient was started on corticosteroids and warfarin. Hypereosinophilia workup was positive for PDGFRA alpha rearrangement. He was diagnosed with primary hypereosinophila syndrome. Imatinib was initiated. The patient was followed up with the hematology clinic, achieved a complete hematologic response with normalized cell count, and remained free from any cardiovascular event at the 8-month follow-up.

Pearls - Apical Obliteration with Biventricular Thrombus




* Cardiac MRI is a valuable test for patients presenting with myocardial infarction with non-obstructive coronary arteries (MINOCA).



* Obliterated apex with apical thrombus on TTE with hypereosinophilia should raise high suspicion for eosinophilic myocarditis.




369. Case Report: Apical Obliteration with Biventricular Thrombus – West Virginia University














CardioNerds (Drs. Richard Ferraro, Gurleen Kaur, and Rupan Bose) discuss the growing epidemic of obesity and dive into the role of its procedural management with Dr. Steve Nissen, Chief Academic Officer at the Cleveland Clinic HVTI and past president of the American College of Cardiology. This is an exciting topic that reflects a major inflection point in cardiovascular care. In this episode, we discuss the importance of addressing obesity in cardiovascular care, as it is a major driver of cardiovascular disease and the progression of associated cardiovascular comorbidities. We look at the role of bariatric surgery and its ability to produce sustained weight loss. Finally, we look into the emerging role of new medical therapies such as GLP1 and GIP agonist medications. Notes were drafted by Dr. Rupan Bose and episode audio was edited by CardioNerds Intern Dr. Atefeh Ghorbanzadeh.

Pearls and Quotes - Procedural Management of Obesity with Dr. Steve Nissen




* Obesity is associated with adverse cardiovascular outcomes. Returning to a healthy weight can largely prevent the downstream consequences of obesity.



* Regarding lifestyle modifications, diet alone is insufficient in sustaining prolonged weight loss. It is associated with short-term weight loss, but it is generally necessary to supplement with exercise and activity to ensure sustained weight loss.



* Bariatric surgery should be considered for patients with BMI ≥40 kg/m2 or BMI ≥35 kg/m2 with obesity-related comorbid conditions who are motivated to lose weight and who have not responded to behavioral treatment with or without pharmacotherapy.



* New emerging medications, including GLP1 receptor agonists, GIP receptor agonists, and glucagon receptor agonists, are beginning to approach weight loss levels that were previously only seen with bariatric surge...

Pearls and Quotes - Clinical Implementation of GLP-1 Receptor Agonists




* GLP-1 agonists work through a variety of mechanisms to counteract metabolic disease. They increase insulin secretion, inhibit glucagon secretion, slow gastric motility, and increase satiety to limit excess energy intake.



* Patients with type II diabetes and an elevated risk for atherosclerotic cardiovascular disease should be considered for GLP-1 agonist therapy regardless of hemoglobin A1c.



* GLP-1 agonists offer significant ASCVD risk reduction even in the absence of diabetes. Newer data suggest a significant reduction in cardiovascular events with GLP-1 agonist therapy in patients who are overweight or obese and have a prior history of heart disease.



* GLP-1 agonists should generally be avoided in patients with a history of medullary thyroid cancer or MEN2. As these medications slow gastric emptying, relative contraindications include history of recurrent pancreatitis and gastroparesis.



* GLP-1 agonists should be initially prescribed at the lowest dose and slowly uptitrated to avoid gastrointestinal side effects.
