(551) Post-Transplant Outcomes in LVAD-BTT Patients: Differences Based on Order of Acceptance of Donor Organs

PurposeIn the new heart transplant (HT) allocation system patients, (pts) with durable left ventricular assist device (LVAD) have worse outcomes. Donor hearts are allocated to recipients according pre-specified criteria (urgency, blood type, size, HLA profile, etc). If an organ is not accepted by selected center it will be offered next center. Unsuitable organs may rejected multiple centers. We studied post-transplant outcomes on LVAD-BTT patients order of acceptance a donor organ.MethodsAdult pts LVAD listed for HT between 10/18/2018 and 12/7/2021 & underwent in were included study. Clinical characteristics recipient at time compared groups. Post-transplant survival was <20 offers those ≥20 offers.Results859 received HT. 592 (68.9%) 267 (31.1%) offers. Notable differences two groups (<20 vs ≥20, respectively): donors more often female (19% 39% p <0.001), had kidney function (Creatinine 1.7 2.1 p=0.035) . There gender mismatch [15% (<20) 26% (≥20) p<0.001] longer ischemic [3.2 3.5 hrs p<0.001]. who attempts likely status 1, 2 or 3 4 (P<0.001). Pts LVADs increased 365 days (94% 90% p=0.047).ConclusionIn system, LVAD-HT that better than attempts. This improved observed despite time, age mismatch, due being stable In organ. Adult 859 p=0.047).
