Abstract
A heart valve assembly includes a prosthesis and a prosthetic valve to replace a preexisting natural or prosthetic heart valve within a biological annulus. The prosthesis includes an annular member, a flexible core at least partially defining a sewing cuff extending radially outwardly from the annular member, a rail ring disposed between the flexible core and the annular member, and a plurality of guide rails extending from the rail ring through respective openings in the flexible core. A fabric covering covers the prosthesis, and the guide rails extend through respective openings in the fabric covering. The prosthetic valve includes a frame including receptacles for receiving respective guide rails. After implanting the prosthesis within a biological annulus, the prosthetic valve is advanced along the guide rails until retention elements on the guide rails engage the receptacles to secure the prosthetic valve relative to the prosthesis.
