Insights

Donation after circulatory determination of death (DCD) heart transplantation (HT) is safe and effective in the US and Europe. Differences in donor/recipient factors exist, but international data collection can refine DCD HT outcomes.

Area of Science:

  • Cardiology
  • Transplant Surgery
  • Organ Donation

Background:

  • Donation after circulatory determination of death (DCD) heart transplantation (HT) is increasingly adopted in the US and Europe.
  • This study analyzes outcomes from DCD HT centers across these regions.

Purpose of the Study:

  • To compare donor and recipient demographics, intraoperative parameters, and outcomes between DCD HT centers in Europe and the US.
  • To evaluate the safety and efficacy of DCD HT internationally.

Main Methods:

  • Retrospective observational study across 22 HT centers in Belgium, Spain, UK, and US.
  • Included patients undergoing DCD HT from program inception through January 1, 2023 (follow-up to January 1, 2024).
  • Primary outcome: 1-year survival; Secondary outcomes: severe primary graft dysfunction, acute cellular rejection.

Main Results:

  • Analyzed data from 223 European and 281 US patients.
  • European DCD donors were older (37 vs. 28 years).
  • European recipients had lower 1-year survival (86.6% vs. 91.8%), with similar 1-month and 3-year survival.
  • Direct procurement and preservation (DPP) showed higher 1-year survival in the US (91.2% vs. 82.6%).
  • Thoraco-abdominal normothermic regional perfusion (taNRP) showed similar 1-year survival between regions.
  • European recipients had higher post-transplant mechanical circulatory support use (17.9% vs. 11%).

Conclusions:

  • DCD HT is safe and effective across US and European centers, despite demographic and outcome variations.
  • International data collection is crucial for identifying strategies to improve DCD HT outcomes.
  • Further research can optimize DCD heart transplantation protocols globally.
