Insights

Thoraco-abdominal normothermic regional perfusion (taNRP) for donor heart recovery in donation after circulatory determination of death (DCD) heart transplantation (HT) led to better outcomes. Recipients of taNRP-retrieved hearts showed reduced severe primary graft dysfunction and acute cellular rejection compared to direct procurement and perfusion (DPP).

Area of Science:

  • Cardiology
  • Transplantation Surgery
  • Organ Procurement

Background:

  • Donation after circulatory determination of death (DCD) heart transplantation (HT) is increasingly common.
  • Effective organ procurement methods are crucial for DCD HT success.
  • Comparing retrieval techniques is essential for optimizing clinical outcomes.

Purpose of the Study:

  • To compare outcomes of DCD HT using two donor heart retrieval methods: thoraco-abdominal normothermic regional perfusion (taNRP) versus direct procurement and perfusion (DPP).
  • To evaluate the impact of retrieval technique on post-transplant survival, primary graft dysfunction, and acute cellular rejection.

Main Methods:

  • Retrospective observational study across 22 international heart transplant centers (Europe and US).
  • Included DCD HT recipients from program inception to January 1, 2023.
  • Compared outcomes between taNRP and DPP retrieval groups, focusing on 1-year survival, severe primary graft dysfunction (PGD), and treated acute cellular rejection (ACR).

Main Results:

  • A total of 504 DCD HTs were analyzed.
  • One-year survival was similar between taNRP (91%) and DPP (88%) groups (P = 0.100).
  • taNRP recipients experienced significantly lower rates of severe PGD (7.6% vs 19.2%; P < 0.001) and treated ACR (13% vs 25%; P < 0.001).

Conclusions:

  • Donor heart retrieval using taNRP is associated with reduced severe PGD and acute cellular rejection in DCD HT compared to DPP.
  • taNRP may represent a more effective organ procurement strategy for DCD heart transplantation.
  • Further investigation with randomized controlled trials is warranted to confirm these findings.
