The present status of heterotopic cardiac transplantation

In the period November, 1974 to May, 1980, 30 patients underwent heterotopic heart transplantation at Groote Schuur Hospital. One patient subsequently underwent retransplantation for rejection. There were no operative deaths. Fifteen patients are alive 4 months to almost 5 1/2 years after transplantation. The 1 year survival rate has been 61%. Three of six patients have survived for more than 4 years. Eight of nine patients whose initial transplant operation was performed during the past 18 months remain alive. Seven patients died from infection, five from rejection, and three from other causes. The advantages of heterotopic over orthotopic heart transplantation, in particular in allowing patients survival even after graft destruction by irreversible rejection, are discussed.
