Abstract

Objective: To report the results of our self-made annuloplasty rings and to identify factors influencing the durability of mitral valve repair.

Methods: Between January 1991 and May 1999, 132 patients with mitral insufficiency underwent mitral valve repair with self-made annuloplasty rings. Mitral insufficiency was due to rheumatic disease in 78 patients, degenerative disease in 44 patients, endocarditis in 6 patients, and congenital heart disease in 4 patients. A total of 85 patients were in functional class II or IV preoperatively. Mid-term follow-up was available in 131 patients from 1 month to 8.1 years (average 2.9 years).

Results: Operative mortality was 0.8 per cent. At 5 years, survival and event-free survival rates were 92 and 82 per cent respectively. One hundred and fourteen patients (97%) were in functional class I, 3 patients (3%) were in class II. Echocardiography at follow-up showed satisfactory mitral valve function. Durability of repair was adversely affected by younger age, rheumatic heart disease, atrial fibrillation, associated diseases, and functional class.

Conclusions: Mid-term results of self-made annuloplasty rings are comparable to commercial ones. Durability was adversely affected by multiple factors.
