Cardiac transplantation in infancy: donors and recipients. Loma Linda University Pediatric Heart Transplant Group.

To evaluate the role of orthotopic cardiac transplantation for infants with lethal cardiac disease, we reviewed the results from our first 25 patients. Data on the donors were also reviewed to define the characteristics of a successful cardiac donor. Patients had transplants between November 1985 and November 1988. Several primary cardiac diagnoses were indications for transplantation, including congestive cardiomyopathy, hypoplastic left-heart syndrome, and other types of native and postoperative complex congenital heart diseases. The ages ranged from birth to 7 months. Of 25 patients, 21 are still alive (84% survival rate) with follow-up from 4 to 40 months. No late deaths have occurred. Long-term immunosuppression was accomplished with cyclosporine and azathioprine. Rejection surveillance was performed noninvasively; only one child required an endomyocardial biopsy. Donors died from a variety of traumatic and metabolic causes, including sudden infant death syndrome. The majority (72%) of donors had a history of cardiac arrest requiring cardiopulmonary resuscitation. One third were receiving inotropic support at the time of cardiac evaluation. We conclude that orthotopic cardiac transplantation is an effective therapy for infants with lethal heart disease. A larger donor pool is required, and many dying infants, despite cardiac arrest and resuscitation, would be suitable donors.
