Mid-term results of Ross procedure: our limited experience

From February 1995 to February 2005, 30 patients underwent the Ross procedure with the root replacement technique. There were 20 males (66.7%) and 10 females (33.3%), aged 13 to 49 years. The diagnosis was aortic stenosis in 12 patients (40%), aortic regurgitation in 10 (33%), mixed stenosis and regurgitation in 6 (20%), prosthetic endocarditis with an aortic root abscess in 1 (3.3%), and a perivalvular leak in 1 (3.3%). There was no early or late death. Six patients (20%) suffered 7 significant operative complications. Over a median follow-up of 65 months (range, 4-114 months), there were 3 re-operations for autograft failure and 2 for homograft failure. No patient experienced a cerebrovascular accident, and all but one were free from endocarditis. Freedom from autograft failure was 94.1% +/- 5.7% at 5 years and 79.5% +/- 10.7% at 8 years, while freedom from homograft failure was 96.6% +/- 3.4% at 5 years and 88.5% +/- 8.3% at 8 years. Our midterm results show that good early and late survival can be obtained in young patients with aortic valve disease. Re-exploration for bleeding and late autograft failure are the main concerns of this challenging operation, especially early in the surgeon's learning-curve.
