Objective. To evaluate the influence of donor LV hypertrophy on the survival of recipients after heart transplantation (HTx). Methods: The study included 446 patients who underwent orthotopic heart transplantation using the biatrial or bicaval technique in the period from 2009 to 2021. The study had a retrospective single-center cohort design. LV hypertrophy was assessed according to ECHO CG data, focusing on measuring the thickness of the walls of the donor heart according to the recommendations of the Ame- rican Society of Echocardiography: < 1.1 – no hypertrophy, 1.1–1.3 cm – mild, 1.4–1.6 cm – moderate LVH, ≥ 1.7 – severe. Control echocardiograms were performed immediately after HTx and 1 year later. According to the above criteria, the first group included recipients of donor heart without LVH and with in- significant LVH, the second group consisted recipients of heart with mod- erate and severe LVH. For a more detailed analysis of survival, 4 subgroups were subsequently identified: no LVH, insignificant, moderate and severe LVH. We analyzed the overall postoperative survival in groups/subgroups, as well as the thickness of IVS and GS in dynamics (after 1 year). The influen
