Impact of donor-to-recipient weight ratio on the hospital outcomes of pediatric heart transplantation

Abstract

Background: Identifying the factors that can influence the prognosis and final outcomes of pediatric heart transplantation is important and makes it possible to prevent complications and improve outcomes. Coordination of donor characteristics with the recipient in terms of sex, weight, body mass index (BMI), and body surface area (BSA) is an important factor that can influence the outcome of the transplantation. There is still no consensus regarding the role of discrepancy in anthropometrics between donors and recipients. The aim of this study was to investigate the relationship between donor and recipient weight mismatch on the early outcomes of pediatric heart transplantation. In this historical cohort study, 80 children who had underwent heart transplantation for the first time between 2014 and 2019 in Shahid Rajaie Cardiovascular Medical and Research Center in Tehran, Iran, were enrolled and divided into three groups according to donor-to-recipient weight ratio (0.8
