Background The enthusiasm about the advantages of a viable autologous transplant faded with recent reports of autograft deterioration and associated reoperations after the Ross procedure. This report evaluates predictors for autograft failure and outcomes extending into the second decade after a Ross procedure. Methods From 1995 through 2012, 645 consecutive patients (mean age, 42.3 ± 14.2 years; 76% males) underwent a Ross operation using mainly the root replacement technique (98%). They were prospectively followed up with clinical and echocardiographic evaluations. Total follow-up was 5,349 patient-years and was 96% complete. Mean follow-up duration was 8.4 ± 4.6 years (range, 0 to 17.4 years). Results Early mortality was 0.9% (n = 6). Cumulative survival at 15 years was 92.7% (95% confidence interval, 90.1% to 95.3%) and did not differ from the general German population (p = 0.261). Freedom from reoperation on the autograft or the pulmonary allograft at 12 years was 91.6% (95% confidence interval, 88.5% to 94.9%) and 95.0% (95% confidence interval, 92.8% to 97.2%), respectively. Sixty-five patients (10.1%) required a total of 78 valve-related reoperations after a Ross procedure (1.5%/patient-year) with a reoperative hospital mortality of 3.8% (n = 3). Forty-seven autograft reoperations were observed in 44 patients (0.87%/patient-year); 22 of them (47%) could be performed as a valve-sparing procedure. Preoperative aortic valve regurgitation and an aortic annulus of at least 26 mm were identified as predictors for autograft failure. Conclusions In this large series, the Ross procedure resulted in excellent long-term survival rates with a low risk of valve-related morbidity and a considerably low rate of reoperations in young and middle-aged patients and should be considered as an important treatment option in this cohort.
