[Results of the lst 100 open-heart operations for mitral valve annuloplasty].

The paper describes the results of 100 annuloplastic operations for the mitral valve with the aid of support rings of varying constructions. Hospital mortality rate was 10%, late mortality rate 4.6%. Five-year survival was 85.5%. In 87.1% of patients the result was good or satisfactory. Unsatisfactory results are due to the initial state of the valve (gross fibrosis, subvalvular adhesions, calcinosis), exacerbation of rheumatic carditis, septic endocarditis. Six patients with unsatisfactory results were reoperated. In 5 the valve was replaced by artificial prosthesis, in one case additional sutures were placed on the fixing ring.
