Abstract

Embodiments of prosthetic valves for implantation within a native mitral valve are provided. A prosthetic valve may comprise a radially compressible main body and a one-way valve portion. The prosthetic valve may further comprise one or more ventricular anchors coupled to the main body and disposed outside of the main body. The ventricular anchors may be configured such that a reduced profile of the prosthetic valve is possible. A space may be provided between an outer surface of the main body and the ventricular anchors for receiving native mitral valve leaflets. The prosthetic valve may include an atrial sealing member adapted for placement above the annulus of the mitral valve. Methods and devices for receiving the native mitral valve leaflets between the ventricular anchors and the main body are described.
