(304) Graft Preservation in Heart Transplantation: Clinical and Histological Results Using Three Different Techniques

PurposeAlongside the classical cold storage with ice, other techniques for graft preservation are increasingly used. The purpose of this study is to analyze results Heart Transplantation (HTx) in relation technique graft.MethodsBetween 2020 and 2022, 55 patients received HTx grafts preserved iced-cold (CS, n=27), normothermic perfusion Organ-Care-System (OCS, n=15), controlled 4°C hypothermia Paragonix SherpaPak (SP, n=13). three groups were compared clinical characteristics, iystological examinations.ResultsCompared CS, OCS SP had a higher IMPACT score (p=0.08) more LVAD support (p=0.01). Extended-criteria donor rate was similar between groups, while ischemic time significantly reduced (p<0.01). 30-day mortality PGD≥moderate grade 1(4%), 2(13%) e 1(7%) (p=0.33) 3(20%) 0% (p=0.11) among SP. Overall cardiac-related 1-year 2(13%), 1(7)% (p=0.03) 0%, 2 (13%), (p=0.21) After prior implant, ice likely show edema, those developped hemorrhagic lesions.ConclusionControlled adopted complex high-risk scenarios satisfactory results. In characteristics donors recipients, could have an impact on outcomes after Alongside graft. Between examinations. Compared lesions. Controlled
