Transplantation of a genetically modified porcine heart into a live human.
Nat Med

Surgery, University of Maryland School of Medicine, Baltimore, MD, USA.
Following our previous experience with cardiac xenotransplantation of a genetically modified porcine heart into a live human, we sought to achieve improved results by selecting a healthier recipient and through more sensitive donor screening for potential zoonotic pathogens. Here we transplanted a 10-gene-edited pig heart into a 58-year-old man with progressive, debilitating inotrope-dependent heart failure due to ischemic cardiomyopathy who was not a candidate for standard advanced heart failure therapies. He was maintained on a costimulation (anti-CD40L, Tegoprubart) blockade-based immunomodulatory regimen.

It's Getting Better All the Time: Decreased Cumulative Incidence of Waitlist Mortality in Pediatric Candidates Following 2018 Heart Allocation Policy Change.

Department of Surgery, NYU Grossman School of Medicine, New York, New York, USA.
Purpose: In October 2018, the OPTN changed adult heart transplant (HT) allocation policy, increasing the number of adult candidates that had higher priority than pediatric candidates, potentially disadvantaging pediatric waitlist registrants.
Methods: To understand the impact of this policy change, we used SRTR data to identify 1469 pre-policy (7/2016-9/2018) and 2901 (10/2018-12/2022) post-policy pediatric (< 18 years) HT registrants. We quantified mortality and transplant risks using weighted cause-specific hazard models, and then using weighted competing risks regression.
Fate of Semilunar Valves From Discarded Hearts at the Time of Pediatric Heart Retransplantation.
Pediatr Transplant
February 2025
The Heart Institute, Cincinnati Children's Hospital Medical Center, Cincinnati, Ohio, USA.
Background: Partial heart transplantation (PHT) is a novel procedure for children in need of a growing valve replacement option. One challenge is identifying suitable donor valves. Semilunar heart valves from patients receiving a retransplant may be a source, however their functionality and growth potential especially at the time of retransplant are unknown.
