Abstract

A prosthetic apparatus for implantation in a native mitral valve includes a main body for placement within the native mitral annulus. The main body is compressible to a radially compressed state for delivery into the heart and is self-expandable from the compressed state to a radially expanded state for implantation. A valve structure is mounted within a lumen of the main body and preferably forms three leaflets made of pericardium. An atrial sealing member is disposed along an atrial portion of the main body and ventricular anchors are coupled to a ventricular portion of the main body. The atrial sealing member impedes the flow of blood between the main body and the native annulus. The ventricular anchors are positioned outside the main body for capturing native mitral valve leaflets between the main body and the ventricular anchors.
