Fifty percent of recipients had prior sternotomy. The mean time from initial declaration of donor death to flush was 9 minutes. Fifteen donor hearts (60%) had a total ischemic time longer than 4 hours, including 1 that was 8 hours. Among recipients, 30-day survival was 96%. Only 1 patient (4%) had severe primary graft dysfunction, and 1 other patient (4%) had secondary graft dysfunction. On initial endomyocardial biopsy, 1 patient (4%) had acute cellular rejection grade 2R; no cases of antibody-mediated rejection were observed.<\/jats:p>\n <\/jats:sec>\n \n Conclusions and Relevance<\/jats:title>\n This study demonstrates the safety, feasibility, and efficacy of REUP for DCD heart recovery without donor heart reanimation in a broad population of donors and recipients and without regard to anticipated ischemic time. Given the high cost and complexity of current DCD heart recovery strategies, as well as ethical concerns surrounding normothermic regional perfusion, REUP may prove to be a promising procurement method. Further study is required to support continued expansion of this novel technique.<\/jats:p>\n
