Predictors and outcomes of severe primary graft dysfunction in heart transplantation: United States cohort analysis.
J Heart Lung Transplant
August 2025
Background: This study aims to assess predictors and outcomes of severe primary graft dysfunction (PGD) in a contemporary United States cohort.
Methods: The United Network for Organ Sharing database was retrospectively reviewed for isolated adult heart transplant recipients (September 2023-March 2025). The population was stratified into severe PGD (left or biventricular dysfunction within 24 hours following transplantation that requires mechanical circulatory support [MCS]) and control cohorts (all other recipients).
Early outcomes of lung transplantation under the composite allocation score system.

Purpose: The Composite Allocation Score was introduced in March 2023 with the goal of improving organ allocation for potential lung transplant recipients. The purpose of this study is to characterize waitlist and post-transplant outcomes for adult lung transplant recipients under the Composite Allocation Score policy.
Methods: We included all adult candidates listed for isolated lung transplantation in the United States from May 2022 to December 2023.
Article Synopsis
- The study aims to compare the occurrence of severe Primary Graft Dysfunction (PGD) in heart transplant recipients from donors after circulatory death (DCD) versus brain death (DBD).
- Out of 2,590 adult heart transplant recipients analyzed, 17.1% were from DCD, with DCD recipients showing a higher rate of severe PGD at 24 hours post-transplant compared to DBD recipients (9.5% vs. 5.1%).
- While the 72-hour severe graft dysfunction rates and 30-day mortality were similar for both groups, PGD rates improved significantly by the 72-hour mark for all recipients.
Background: Lung transplant surgery creates surgical pulmonary vein isolation (PVI) as a routine part of the procedure. However, many patients with pretransplant atrial fibrillation continue to have atrial fibrillation at 1 y. We hypothesized that the addition of electrical PVI and left atrial appendage isolation/ligation (LAL) to the lung transplant procedure restores sinus rhythm at 1 y in patients with pretransplant atrial fibrillation.

Objective: We aimed to evaluate the safety and efficacy of delaying lung transplantation until morning for donors with cross-clamp times occurring after 1:30 am.
Methods: All consented adult lung transplant recipients between March 2018 and May 2022 with donor cross-clamp times between 1:30 am and 5 am were enrolled prospectively in this study. Skin incision for enrolled recipients was delayed until 6:30 am (Night group).
