[Surgical correction of mitral valve stenosis and its recurrence].
The article analyses the results of surgical treatment of 1,394 patients with mitral stenosis who were operated on in the period between January 1, 1986 and April 1, 1989. Hospital mortality was 2.0%. Distinct indications for transventricular commissurotomy and mitral valve prosthetics were determined. The choice of the method for mitral stenosis correction was based on the character of the morphological changes in the cusps and subcuspal structures, which were determined during echocardiographic examination. With proper indications transventricular commissurotomy presents a small risk. Hospital mortality was 0.8% in mitral stenosis (among 1,039 patients who underwent operation 8 died) and 2.5% in recurrent stenosis (among 197 patients 5 died). Lethal outcomes were not encountered in stage 11, the mortality rate was 0.6% in stage III and 2.2% in stage IV. Mitral valve prosthetics was performed in 158 patients with 15 (9.5%) lethal outcomes. Hospital mortality was 4.5% in stage III and 10.3% in stage IV of the disease. In the group of patients with mitral stenosis hospital mortality was 7.5% (93 patients underwent operation). Hospital mortality after operations for recurrent mitral stenosis (65) was 12.3%. The initial severity of the patients' condition is still the main factor which influences unfavorably of the immediate results of mitral valve prosthetics.
