Abstract
Background: Meaningful analysis of survival and risk factors for death in children who undergo heart transplantation is problematic because of the small number of heart transplantations performed at individual institutions. Methods and Results: To more accurately examine survival and risk factors for death in children undergoing heart transplantation, we analyzed 191 patients between 1 and 18 years old who received transplants at 22 centers in the Pediatric Heart Transplant Study between January 1, 1993, and December 31, 1994. Cardiac diagnosis was congenital heart disease in 74 patients (39%), dilated cardiomyopathy in 73 (38%), and other in 44 (23%). Actuarial survival was 93% at 1 month, 82% at 1 year, and 81% at 2 years after transplantation. The major causes of death (n=31) were rejection (29% of deaths), early graft failure (19%), infection (16%), sudden death (13%), and other causes (23%). By multivariate analysis, risk factors for death were assist devices (P=.02), nonidentical ABO blood types (P=.05), and younger age (P=.10). Conclusions: Contemporary survival for pediatric heart transplant recipients ≤1 year old is comparable to survival after adult heart transplantation. Risk factors for death are the need for assist devices, nonidentical ABO blood types, and younger age. Rejection is the most common cause of death after pediatric heart transplantation.
