To assess survival after the development of transplant coronary artery disease, annual angiography reports from 353 heart transplant recipients were reviewed. Fifty-four patients who survived beyond 1 year and in whom moderate-to-severe proximal or midvessel coronary artery disease developed were identified. Moderate-to-severe proximal or midvessel coronary disease was defined for this study as a 40% or more stenosis in 1 or more primary or secondary epicardial arteries. Actuarial survival (Kaplan-Meier) from the time of disease detection in those 54 patients was 67% at 1 year, 44% at 2 years, and 17% at 5 years. Actuarial survival was reduced proportionate to disease severity. Survival for single-vessel disease (> or = 40% stenosis) was 64% at 1 year, 36% at 2 years, and 22% at 5 years. Survival was significantly worse with triple-vessel disease (13% at 2 years; p = 0.01) and intermediate for double-vessel disease (41% at 2 years; p = 0.01). Of 19 patients who underwent retransplantation for coronary artery disease, 13 patients (68%) died at a mean of 24 +/- 20 months (range, 1 to 59), and of 15 patients from whom postmortem or angiographic data were available, 11 patients (73%) showed recurrence of significant coronary artery disease in the new graft. Identification of moderate or severe proximal or midvessel coronary disease at angiography predicts an overall mortality rate of more than 50% at 2 years. The poor survival rate in those who underwent retransplantation (around 50% at 4 years) and the high rate of redevelopment of coronary disease suggest that retransplantation should be reserved for selected candidates with angiographically severe disease, if used at all.
