METHOD OF IMPLANTATION OF PROSTHESIS OF HEART VALVE INTO AORTAL POSITION IN MITRAL-AORTAL PROSTHETICS Russian patent published in 2017 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: when combined implantation of prostheses MK and AK, after first excision of pathologically altered MK, implant the prosthesis of the valve in the mitral position. Then, after excision of abnormally altered AK, the circumference of the CFR is divided into two semicircles so that the middle of the first semicircle adheres to the region of the mitral-aortic contact. U-shaped stitches are applied along the first semicircle perimeter, puncturing both needles in from the ventricular, and out - from the aortic surface of CFR. Next, U-shaped sutures are applied along the second semicircle perimeter. At that, both needles are punctured in from the aortic, and out - from the ventricular surface of CFR. In the area of each boundary between the semicircles, a Z-shaped suture is applied. Parallel stitches of the Z-shaped suture are formed by passing needles through the CFR similarly to the previously applied sutures. Then, the needles of all superimposed sutures are passed through the prosthesis cuff, beginning with its surface facing the ventricle. The prothesis is placed in the CFR area, and the applied sutures are knotted.

EFFECT: method allows to prevent the dysfunction of the occlusal element of the rotary-disc prosthesis AK in combined mitral-aortic prosthetics by providing an optimal interposition of implantable prostheses by combining the techniques of intrasupranulyarnoy technique with implantation of the valve prosthesis in the aortic position.
