Abstract

Pediatric heart failure and transplantation carry associated risks for kidney failure and potential need for kidney transplant following pediatric heart transplantation (KT/pHT). This retrospective, United Network of Organ Sharing study of 10,030 pediatric heart transplants (pHT) from 1987-2020 aimed to determine the incidence of waitlisting for and completion of KT/pHT, risk factors for KT/pHT, and risk factors for non-receipt of a KT/pHT. Among pHT recipients, 3.4% were waitlisted for KT/pHT (median time of 14 years post-pHT). Among those waitlisted, 70% received a KT/pHT and 18% died on the waitlist at median time 0.8 years from KT/pHT waitlisting (median age of 20 years). Moderate-high sensitization at KT/pHT waitlisting (calculated panel reactive antibody (cPRA) ≥ 20%) was associated with lower likelihood of KT/pHT (adjusted hazard ratio (aHR)=0.67; 95% CI=0.47, 0.95). Waitlisting for HT simultaneous with KT (aHR = 3.73; 95% CI = 2.01, 6.92) was associated with increased risk of death on the KT/pHT waitlist. While prevalence of KT/pHT is low, there is substantial mortality among those waitlisted for KT/pHT. These findings suggest a need to consider novel risk factors for non-receipt of KT/pHT and death on the waitlist in prioritization criteria/guidelines for simultaneous heart-kidney transplantation.
