摘要：
The invention relates to the field of medicine and can be used in cardiac surgery with surgery to replace diseased natural aortic and mitral valves of the human heart. The technical result achieved when using the present utility model is to reduce the risk of thrombogenesis and hemolysis, improved washing of the heart valve prosthesis elements of the blood, increase in hemodynamic efficiency and achieved in that the heart valve prosthesis comprising an annular body delimited by two end faces facing the direct and reverse blood flow, mounted in the housing with the possibility of opening and closing of the orifice housing the locking element in the form of two and Vorokov, upstream and downstream surfaces of which are formed as surface of rotation and travel stops of the locking element, at least upstream and downstream surface of the flaps facing the forward and reverse flow of blood, it is in the form of the surface of a body of rotation, and the projection clamping surface flaps at one of the ends of the housing is formed S-shaped, the travel stop of the locking member is in the form of opposed pairs of projections at the end facing the backflow of blood and the interaction ystvuyuschih with valves for opening and closing, wherein each projection of one of the pairs of travel stop of the locking element has an inner flat and the side, a part of the surface of the rotating body, the surface, and each projection of the other pair limiter locking member stroke is provided with a groove having a cylindrical cross cross section, each of the flaps on the outer side, facing the direct blood flow, stroke limiter truncated projections having an inner flat surface so that its inner flat portion corresponds to the flat truncated portion of the sash, with a truncated portion of each leaflet is provided with protruding segment located on an inner side ascending and descending surface of both the flaps are in the form of the cone surface and the maximum inclination angle of the
