Background: The new heart transplant allocation criteria prioritize inpatients who require temporary mechanical circulatory support and give lower urgency to candidates on a durable left ventricular assist device (LVAD) who require a device exchange. This study explores whether the latter group should warrant higher priority to reduce wait-list mortality.
Methods: This is a retrospective observational study of 13,113 adult heart transplant candidates in the Organ Procurement and Transplantation Network database who underwent LVAD implantation between 2007 and 2017. It evaluates the impact of LVAD exchange on the composite endpoint of death or removal from the wait list owing to worsening medical condition 1 y after device implantation.
Results: There were 1085 pump exchanges in 954 patients (7% of candidates), of which 22% were women. The pump exchange rate was 5.92 events per 100 patient-years. One-year survival was lower for those who required a pump exchange (76.3% versus 88.5%, logrank P < 0.001). This was congruent with the risk-adjusted mortality 1-y after implantation (hazards ratio: 2.56, 95% confidence interval: 2.18-3.00, P < 0.001).
Conclusions: These findings indicate that among candidates awaiting heart transplantation with a durable LVAD, undergoing pump exchange doubles the risk of 1-y mortality. Giving priority to these candidates may reduce wait-list mortality.

Background: Patients with end-stage kidney disease (ESKD) are at high risk for coronary artery disease. We investigate the trends and outcomes of percutaneous coronary intervention (PCI) for stable ischemic heart disease (SIHD) in patients with ESKD.
Methods: We utilized the United States Renal Data System [2010-2018] to include adult patients with ESKD on dialysis for at least 3 months who underwent PCI for SIHD.

Introduction: Organ transplant recipients face a substantial risk of developing posttransplant lymphoproliferative disorders (PTLD). In over 90% of cases with B-cell PTLD following solid organ transplantation, the Epstein-Barr virus (EBV) genome is promptly identified, usually within the initial year. A continuing discussion revolves around the efficacy of antiviral prophylaxis in mitigating the incidence of PTLD in solid organ transplant (SOT) patients.

Allogeneic chimeric antigen receptor (CAR) T cells targeting disialoganglioside-GD2 (ALLO_GD2-CART01) could be a therapeutic option for patients with relapsed or refractory, high-risk neuroblastoma (r/r HR-NB) whose tumors did not respond to autologous GD2-CART01 or who have profound lymphopenia. We present a case series of five children with HR-NB refractory to more than three different lines of therapy who received ALLO_GD2-CART01 in a hospital exemption setting. Four of them had previously received allogeneic hematopoietic stem cell transplantation.

Targeting the cardiomyocyte cell cycle is a promising strategy for heart repair following injury. Here, we identify a cardiac-regeneration-associated PIWI-interacting RNA (CRAPIR) as a regulator of cardiomyocyte proliferation. Genetic ablation or antagomir-mediated knockdown of CRAPIR in mice impairs cardiomyocyte proliferation and reduces heart regenerative potential.

Introduction: Whether the implementation of a multimodal prehabilitation program is effective and safe for high-risk heart or lung transplantation candidates, whose condition prevents hospital discharge, is unclear.
Methods: We conducted a retrospective study at a cardiothoracic transplant center in Chile. Two cohorts of hospitalized patients listed for heart or lung transplant were studied: the first underwent traditional (historical) and nonstructured prehabilitation, and the second underwent protocol-driven multimodal prehabilitation (MP).
