1036 Gender Equality in Heart Transplantation: A Single Centre Study

Abstract

Abstract Background International Society for Heart and Lung Transplantation categorises female gender in donor/recipient, as a significant risk factor for mortality after heart transplantation. Further, donor-recipient gender mismatch is also reported to be a determinant of post-transplant morbidity/mortality. To examine the effect of gender in survival outcomes, we conducted a retrospective study. Method Population comprised of 298 patients undergoing heart transplantation from 2001 to 2021, divided into four groups on the basis of donor and recipient matching. Group A consisted of men who received male donor-hearts, group B of women who received female donor-hearts, group C of women who received male donor-hearts, and group D of men who received female donor-hearts. Standard heart transplantation protocols were applied to all patient groups for graft preservation, surgical technique, donor-recipient size matching, induction & immunosuppressive-therapy. Results The study groups were found to be homogeneous to the major preoperative- risk- factors (aetiology, transplantation status, donor-recipient-age, total ischemic time). Donor gender, recipient gender and donor-recipient gender mismatching did not significantly modify the short and mid-term survivals, functional recovery, and primary graft dysfunction post-surgery. Conclusions Even though previous reports suggest that gender negatively affects survival, this proved to have no influence on the outcomes in our study. These results can be explained by a correct donor-recipient size matching. The well-documented female recipients’ tendency to more frequent and fatal rejection was not confirmed in our experience. The patient's age at transplantation, the routine use of induction therapy and an aggressive immunosuppressive regimen may be the substrate of these findings.
