FIELD: medicine; cardiovascular surgery.
SUBSTANCE: heart valve bioprosthesis comprises a flexible bearing frame formed by three axially symmetrical arches joining the rack tops. The commissure tops are formed by shutters connected by sutures and fixed on the bearing frame enclosed in a biocompatible material, e.g. xenopericardium. The enclosure shaped as the top edge frame, while its bottom part is shaped as an edge of fibrous ring of recipient aortic valve and forms an attached cuff. A bioprosthesis is made of valve complexes of mammal hearts or pericardium.
EFFECT: inventions prevent stenotic effect and allow reducing operation time.
