Longitudinal Changes in Estimated Glomerular Filtration Rate Following Repeat Heart Transplant in Children and Young Adults.

Background: Chronic kidney disease (CKD) is common after heart transplantation (HT). There are scarce studies looking at longitudinal changes in estimated glomerular filtration rate (eGFR) after repeat HT (RT) and risk factors for the presence of CKD3 post-RT.

Methods: First-time HT recipients (FT) were matched with RT, based on age at transplant, sex, race, and transplant era.

Changes in estimated glomerular filtration rate over the first year following repeat heart transplant in children and young adults.

Background: Renal function is reduced in patients undergoing heart transplant due to hemodynamic compromise, cardiorenal syndrome, and nephrotoxin exposure. No current studies evaluate renal function in retransplants.

Methods: We reviewed all heart transplants at our center from 1995 to 2021 and matched first-time heart transplants with retransplants, based on age at transplant, sex, and race.
