Abstract
BACKGROUND: We evaluated the effectiveness and durability of the leaflet extension technique for correction of aortic regurgitation (AR) and the long-term clinical results. METHODS: Between March 1995 and August 2004, 41 consecutive patients were included. The mean age was 32.2 +/- 13.9 years. The causes of AR were rheumatic in 31 patients (75.5%), degenerative in 2 patients (4.9%), bicuspid aortic valve in 4 patients (9.8%), infective endocarditis in 1 patient (2.4%), and congenital in 3 patients (7.3%). Leaflet extensions were performed in three leaflets for 32 patients, two leaflets for 3 patients, and only one leaflet for 6 patients. The mean follow-up duration was 92.9 +/- 48.4 months. RESULTS: There were no early deaths and 2 late deaths. One patient died of cancer and the other patient died of infective endocarditis. The cardiac-related mortality was 2.4% (1 of 41 patients). During a mean follow-up of 7 years, severe AR was detected in 1 patient and moderate AR in 6 patients (17.0%; 7 of 41 patients). The causes of recurrent AR were infective endocarditis in 3 patients, disease progression in 3 patients, and Behçet's diseases in 1 patient. We performed 6 reoperations (14.6%), 3 in patients owing to infective endocarditis, 2 in patients owing to disease progression, and 1 in a patient owing to the suture dehiscence associated with Behçet's disease. The cumulative survival was 92.6% at 13 years. Freedom from recurrent AR was 97.5% at 5 years, 81.7% at 10 years, and 68.1% at 13 years. CONCLUSIONS: The long-term durability of the leaflet extension technique was acceptable. The reoperations increased with time, but pericardial leaflet dysfunction was not the cause.
