VALVE-CONTAINING AORTIC ROOT PROSTHESIS

摘要

FIELD: medicine.SUBSTANCE: invention refers to medical equipment and may be used in cardiac surgery for replacement of an injured aortic root with an aortic valve. A valve-containing aortic root prosthesis comprises a vascular prosthesis 1 with a cuff 3 attached from a proximal side, and a valve 4 inserted in the cuff 3. The prosthesis is provided with a ring plate 5 attached to the cuff 3 along the internal perimetre. The plate 5 is pulled to the vascular prosthesis to approach the cuff 3, and intraoperatively anchored over the cuff 3 to seal a junction of the cuff and coronary tendons.EFFECT: higher reliability and reduced risk of postoperative complications associated with a leaking junction of the prosthesis and the coronary tendons of the valve prosthesis.4 cl, 2 dwg
