[Results of the aortic valve prosthesis with a follow-up period of over 3 years].
The results of the aortic valve prosthetics in 71 patients discharged from the A.N. Bakulev institute of Cardio-Vascular Surgery of the AMS of the USSR as far back as three and more years ago are analyzed. All these patients had been given implanted a Soviet-made ball-type prosthesis, model AK4-02. In 5 patients some additional operative interventions were performed. No indirect action anticoagulants were used. Nine patients (12.7 per cent) died late after the operation. Good, persistent results were achieved in 48 cases (67.6 per cent) with follow-up period ranging from 3 to 9 years. Major causes responsible for a reduced effect of surgery were thromboembolic complications, paravalvular fistulas and also uncorrected or inadequately corrected concomitant failures of other valves. Ways of increasing the effective prosthetics of the aortic valve with the ball-type prosthesis are discussed.
