On May's JHLT: The Podcast, we feature two manuscripts from the May issue of The Journal of Heart and Lung Transplantation.

First, the editors explore a study entitled "Donor hyperoxia is a novel risk factor for severe cardiac primary graft dysfyunction," which comes from Kransdorf and colleagues at Cedars Sinai Medical Center in Los Angeles.

The editors welcome first author Evan Kransdorf, MD, PhD, to share how he transitioned from oncology to heart failure and transplantation, and to talk about the findings of the study. The Digital Media Editors want to know how machine learning came to be a part of the study, what other donor-specific predictors might contribute to severe PGD, and whether DCD and DBD donors had different outcomes.

Next, the editors welcome first author Danny Ramzy, MD, PhD, from the UTHealth McGovern School of Medicine in Houston to discuss the paper, "Improved clinical outcomes associated with the Impella 5.5 compared to the Impella 5.0 in contemporary cardiogenic shock and heart failure patients."

The digital media editors dig in with Dr. Ramzy on why Impella 5.5 has better outcomes and if this outcome holds in multivariable models, why the survival outcomes were so much higher than published survivals for patients with cardiogenic shock, and what follow up studies might get the answers they're looking for.
