[Causes of failure analysis after cardiac transplantation. From a consecutive series of 91 cases].

Ninety-three cardiac transplantations were carried out in 91 patients (2 retransplantations) between March 1st 1987 and November 1st 1989, in 84 adults and 7 children under 15 years of age. The indications were dilated cardiomyopathy (48%), ischemic cardiomyopathy (35%), decompensated valvular heart disease (11%), congenital heart disease (3%) and two cases of Uhl's anomaly. Twelve patients underwent transplantation after external circulatory assistance (13%), 11 patients after inscription on the list of extreme emergencies, and 68 on an elective basis (74%). The postoperative immunosuppressive protocol was triple therapy: Ciclosporine, Azathioprine and Prednisone. Three of the children died. The early adult mortality was 9 cases (10.7%). It was 8% in patients operated electively. Major infectious complications occurred in 10 patients (11%). Rejection was looked for by systematic endomyocardial biopsy and echocardiography. Three hundred and forty-nine biopsies were made. Thirty-five patients (44%) had no problems of rejection. Seventy-nine patients have now been followed up for an average of 19 months. There were 7 late deaths. Seventy seven per cent of the survivors are asymptomatic. Acute rejection and transplant dysfunction were the two main causes of early mortality after cardiac transplantation. Although the long-term prognosis is uncertain, the medium-term results are very encouraging.
