Pediatric retransplantation.
Previous studies have attempted to outline the efficacy of heart retransplantation in adults. A limited number of these retransplantation procedures have been performed in children; however, no study to date has evaluated the risk of heart retransplantation in this specific patient population. We conducted a retrospective review of 17 pediatric (non-neonatal) heart transplant recipients who subsequently underwent heart retransplantation. Thirteen male and four female patients underwent retransplantation at four different institutions between 1974 and 1992. Patient age at the time of primary transplantation ranged from 2 to 19 years (mean, 12.5 years) and from 3 to 30 years (mean, 16 years) at retransplantation. The time interval between transplantation procedures ranged from 2 days to 15.6 years and was not predictive of patient outcome. Follow-up after retransplantation ranged from 1 day to 11 years (mean, 2.8 years). All patients were New York Heart Association class 3 or class 4 at the time of retransplantation. After retransplantation all survivors were New York Heart Association class 1. No patient had mechanical device implantation or extracorporeal membrane oxygenation bridge-to-transplantation at primary transplantation or retransplantation. The indication for retransplantation was transplant coronary artery disease (TxCAD) in seven patients (41.2%), acute rejection in four (23.5%), chronic rejection in one (5.8%), chronic rejection associated with TxCAD in four (23.5%), and intraoperative donor organ failure in one (5.8%). No significant difference occurred in linearized rates of rejection or infection or in actuarial freedom from rejection or infection when secondary grafts were compared with primary grafts in patients undergoing retransplantation.(ABSTRACT TRUNCATED AT 250 WORDS)
