ABSTRACT
The article presents three clinical observations of successful thrombectomies in patients with thromboses of modern bicuspid prostheses of the heart (MEDINZH-2, Carbo Medics) which was 21.4% of all operations (14) for acute thrombosis of the artificial heart valve. It should be taken into consideration that such kind of operation is possible when there are easily removed small loose thrombus, good fixation of the prosthesis and a complete endothelization of the cuff.

Operations were performed on 183 patients with infective endocarditis and injury of the valve apparatus of the heart. Duration of the disease was from 5 weeks to 9 years. Insufficiency of circulation of the III-IV functional class was noted in 92% of the patients. High activity of the infective process observed in 30% of the patients by the moment of operation did not influence the results of surgical treatment. Postoperative lethality was 7.6%.

The authors share the observations from their cardiosurgical practice showing that one of the causes of sudden death or of rapid worsening of the state of patients with implanted bicuspid artificial valves might be their dysfunction resulting both from breakage of the hinged mechanisms of the valve with its dislocation and migration and from the disturbed mobility of the valve cusp due to a thrombus formed in the atrium. The observations show that the "ideal" construction of the valve is to be created.
