Do DCD hearts from older donors need to be reanimated before transplantation?

Our early @VUMChealth experience suggests they may not.

Published today in @CircAHA : 20 DCD heart transplants from donors ≥40 years using Rapid Ultraoxygenated Recovery (REUP) without preimplant reanimation.

✅ 0/20 severe PGD
✅ 0% discard rate
✅ 281 min median ischemic time
✅ 95% 90-day survival

These early, single-center data challenge the assumption that donor age ≥40 requires reanimation before transplant.

It may be time to redefine perfusion adequacy.
Our JTCVS study shows that longitudinal oxygen delivery & extraction trajectories—not delivery thresholds alone—are independently associated with morbidity & AKI in CABG.
Perfusion is dynamic.
