Abstract
A mechanical heart valve implantable as heart valve replacement comprising of an annular valve body with a central orifice and an exterior surface incorporating a suture ring having a plurality of suture tunnels, and a valve implantation flap assembly disposed on the valve body surface and wrapping around the suture ring. The inside lumen carries the occluder mechanism. The valve holder comprises of at least two parts, both parts having suture guiding grooves on the outer surface corresponding to and matching with the tunnels on the suture ring, such as to form a continuous path for the sewing material. The parts of the valve holder can be detached separately from the valve after taking all the sutures, the part on the ventricular side before lowering the valve into the heart and the other part after lowering and positioning the heart valve in the; desired position inside the heart.
