[Problems of surgical treatment of dysfunction of heart valve prosthesis]

The article generalizes experience in surgical treatment of disturbed functioning of heart valve prostheses. Functioning was impaired in 3.2% of 5113 prostheses. Operations were repeated in disturbed functioning of heart valve prostheses in 58 (35.4%) patients, in 7 of them the intervention was repeated twice. Closure of fistulas (26.2%) is possible only in moderate paravalvular+ insufficiency which is not connected with septic endocarditis. The authors emphasize the great risk of repeated operations, which calls for special attention to be paid to the prevention of disturbed functioning of heart valve prostheses.
