Prognosis analysis of marginal heart donor in heart transplantation / 中华胸心血管外科杂志

ABSTRACT

Objective:To investigate the prognosis of marginal donor heart in heart transplantation.Methods:The clinical data of consecutive heart transplant recipients and donors in Zhengzhou 7th. People’s Hospital from April 2018 to November 2022 were retrospectively included. According to the definition of marginal donor hearts, the patients were divided into conventional donor hearts group (117 cases) and marginal donor hearts group ( 62 cases), the data before and after heart transplantation of the two groups were analyzed.Results:The main reason for the formation of marginal donor hearts was the cold ischemia time of donor hearts >6 h; it was easier to receive marginal donor hearts with ECMO and MV before operation; the use of marginal donor hearts in heart transplantation increased postoperative mechanical ventilation time, surgical post-intensive care unit length of stay; patients with marginal donors had lower survival than conventional donors, but did not produce a significant difference in survival after heart transplantation.Conclusion:The application of marginal donor heart in heart transplantation is an effective method to solve the shortage of heart organs and reduce the death of transplant waiting persons.
