JHLT: The Podcast – Détails, épisodes et analyse

On this episode of JHLT: The Podcast, the Digital Media Editors host a discussion on the paper, "Impact of donor specific antibodies on longitudinal lung function and baseline lung allograft dysfunction."

They are joined by the first author, Muhtadi Alnababteh, MD, Assistant Professor at the University of Maryland and Staff Clinician at the National Institutes of Health, and senior author Michael Keller, MD, of the Pulmonary and Critical Care division at the University of Maryland.

The discussion explores:

• Common characteristics of patients who developed donor-specific antibodies (DSA)
• Differences in outcomes depending on when DSA developed
• Associations between the development of DSA and antibody-mediated rejection, and related time frames

On this episode of JHLT: The Podcast, the Digital Media Editors invite co-lead author Nir Uriel, MD, Director of Advanced Heart Failure and Cardiac Transplantation at New York Presbyterian Hospital and Professor of Medicine at Columbia University.

Dr. Uriel joins to discuss the work of the Cardiogenic Shock Working Group (CSWG) and their recent paper, "Outcomes of patients supported on Impella 5.5 for more than 14 days: A Cardiogenic Shock Working Group registry analysis."

The discussion explores:

• Why patients on longer duration of MCS had better survival but maintained similar rates of serious adverse events (SAEs)
• Why the study might show fewer SAEs than the literature historically shows
• How temporary MCS devices are selected in clinical settings in patients with cardiogenic shock
• The ongoing and upcoming activities of CSWG

Returning for a second study this month, the JHLT Digital Media Editors invite first author Charlotte Van Edom to discuss the paper, "Apixaban plasma levels in patients with HeartMate 3 support."

As a cardiologist in training and a PhD candidate at the University Hospitals Leuven in Belgium, Van Edom's work focuses on hemocompatibility and mechanical circulatory support, covering both short-term and long-term support.

The episode explores:

• The evolution of the use and understanding of direct oral anticoagulants (DOACs) during LVAD support, including the increased focus on Factor Xa inhibitors
• Encouraging findings from the study and what clinical practices might need to change if introducing apixaban
• Additional studies exploring DOACs in LVAD patients

On this episode of JHLT: The Podcast, the Digital Media Editors invite author Ioana Preston, MD, to discuss the paper, "Efficacy and safety of sotatercept across ranges of cardiac index in patients with pulmonary arterial hypertension: A pooled analysis of PULSAR and STELLAR."

Dr. Preston is the director of the pulmonary hypertension center at Lahey Hospital and Medical Center in Burlington, Massachusetts, and has over 20 years of experience in caring for patients with PH, as well as multiple clinical trials in PH.

The episode explores:

• What makes sotatercept unique as the first "biologic" in the treatment of PAH
• Hypotheses about the mechanism of action in sotatercept
• Sotatercept's interaction with mPAP and what it indicates about the drug's action on the pulmonary vasculature

Those involved in the heart failure and mechanical circulatory support should tune in again later this month for a study on apixaban plasma levels in patients with HeartMate 3 support.

Returning for a second study this month, the JHLT Digital Media Editors conduct an internal discussion on the paper, "Safety and efficacy of riociguat in patients with pulmonary arterial hypertension and cardiometabolic comorbidities: Data from interventional clinical trials."

The episode explores:

• The aging PAH population and the new comorbidities that must be considered in research
• How the study augments and expands on recent standards, like the 2022 ESC/ERS guidelines for pulmonary hypertension
• Limitations on the study and opportunities for future research

On this episode of JHLT: The Podcast, the Digital Media Editors invite lead author Jan Van Slambrouck, MD, to discuss the paper, "The effect of rewarming ischemia on tissue transcriptome and metabolome signatures: A clinical observational study in lung transplantation."

Dr. Van Slambrouck is a general surgeon who's just finished his PhD training at the KU Leuven lab of respiratory disease and thoracic surgery in Belgium.

The episode explores: 

• How rewarming ischemia time (RIT) affects donor lungs, especially on the molecular level
• The pace of rewarming and how prior literature prepared the team to track and evaluate it
• Clinical strategies to reduce RIT and directly address molecular changes

Those involved in the pulmonary vascular disease space should tune in again later this month for a study on the safety and efficacy of riociguat in patients with PAH.

Returning for a second study this month, the JHLT Digital Media Editors invite lead author Oliver J.F. Weiner, to discuss the paper, "Sympathetic reinnervation in cardiac transplant recipients: Prevalence, time course, and association with long-term survival."

Dr. Weiner is currently an out of training registrar at Monash Health in Melbourne, Australia, but will soon return to his home of the UK to begin internal medicine training with the intention becoming a cardiologist. He is especially interested in advanced heart failure and electrophysiology.

The episode explores:

• The uncertainty around clinical influences on reinnervation
• The importance of this single-center study in expanding the literature
• Potential future treatment options
