[Multicomponent reconstructive operations on the mitral valve].
Between 1978 and 1990, 134 reconstructive operations were conducted on the mitral valve in its predominant incompetence. 50% of patients were related to functional class IV (NYHA), 76.1% had atrial fibrillation. In 44 (32.8%) patients interventions were conducted at the same time on other valves. The valvular disease was caused by rheumatism in 78.3%, congenital pathology in 10.4%, and impaired connective-tissue structure in 10.4% of cases. Hospital mortality was 5.9% (8 patients). Mortality in the group of patients with isolated annulovalvuloplasty was 4.4%. The immediate results were good in 93.3% of patients. The late results were studied in 120 patients during a maximum follow-up period of 12 years. The actuarial survival value by the 12th follow-up year was 83.5%. By that time there was no need for a repeated operation in 88.4% of patients, thrombolytic complications did not develop in 91.2% of cases, 96.7% of patients belong to functional classes I and II.
