BACKGROUND: Heart transplantation following donation after circulatory death (DCD HT) has short-term survival outcomes comparable to donation after brain death and has led to a significant increase in transplantation volume. The U.S. experience with the normothermic regional perfusion (NRP) DCD HT procurement method has not been evaluated.
OBJECTIVES: The aim of this study was to examine short-term outcomes associated with NRP vs direct procurement and perfusion (DPP) methods used during DCD HT in the United States.
METHODS: The UNOS (United Network for Organ Sharing) registry was queried for all adult (age ≥18 years) heart recipients and corresponding donors of controlled DCD HT from January 2019-December 2023. Transplantations were stratified by NRP or DPP reperfusion methods. The primary outcome was overall survival.
RESULTS: A total of 918 heart donors and recipients met inclusion criteria, including 622 (68%) DPP and 296 (32%) NRP transplantations. Unadjusted Kaplan-Meier survival analysis demonstrated improved short-term survival associated with NRP (log-rank P = 0.005). After adjustment, DCD HT with NRP was independently associated with improved survival (HR: 0.39 [95% CI: 0.22-0.70]; P = 0.002). A propensity-matched analysis similarly demonstrated a cumulative survival benefit to NRP (log-rank P = 0.006).
CONCLUSIONS: In this largest national series of DCD HT procurement perfusion strategies, NRP is associated with improved short-term survival as compared with DPP. This study evaluates the U.S. early experience with DCD HT, and longer-term follow-up data are needed to further assess the impact of DPP and NRP methods on post-heart transplantation outcomes.
