Heart transplantation among 233 infants during the first six months of life: the Loma Linda experience. Loma Linda Pediatric Heart TransplantGroup.
Two hundred thirty-three heart transplantations were performed in infants during their first 6 months of life at Loma Linda University between November, 1985 and June, 1999. Survival has now exceeded 13 years. Nearly 70% of infants are expected to live at least 10 years. Those transplanted during the first 30 days of life have about a 15% survival advantage at 10 years. Scarcity of donors continues to limit the transplantation effort. While acute rejection is the most common cause of late mortality, posttransplant coronary artery disease (PTCAD) is the leading cause of graft loss affecting 22 recipients (9.5%). The majority of patients are asymptomatic prior to diagnosis of PTCAD and are either retransplanted or dead within 6 months. Retransplantation (9 of 11 retransplantations for PTCAD) has been highly successful, with 10 year actuarial survival of 91%. Posttransplant lymphoproliferative disease (PTLD) has been found in only 7 patients (3%), most commonly in lymph nodes. Causes of late mortality include acute rejection (n = 16), PTCAD (n = 9), infection (n = 7), PTLD (n = 2), chronic graft dysfunction (n = 2), arrhythmia (n = 1), recurrent pulmonary vein stenosis (n = 1), and other noncardiac causes (n = 4). Infant psychomotor development is mildly delayed although cognitive development is normal. School-age children are performing at the level of their peers with average achievement and low average intelligence testing. Heart transplantation is durable therapy for newborns and infants with structurally incurable and end-stage myopathic heart disease.
