Abstract: A partial valve prosthesis includes a framework configured for following a shape of a portion of the native valve annulus when implanted into the native valve annulus, the framework including securement features for anchoring the framework to an inner periphery of the native valve annulus and retaining at least one leaflet configured to replace a corresponding one of the plurality of native leaflets; and at least one leaflet secured to the framework. Additional embodiments and methods are disclosed.

Abstract: An implantable prosthetic posterior mitral valve is described where one variation generally includes a frame. A posterior leaflet having one or more scallops may be connected to the frame such that the scallops extend from the frame for coaptation against a native anterior leaflet when the frame is deployed. At least one arm member may be connected to the frame such that the arm member extends laterally in a curved configuration configured to approximate a curvature of a native mitral annulus when the frame is deployed, and an anchoring leg may be connected to the frame and extend in a superior direction from a posterior side of the frame and defines a capture region between the anchoring leg and the posterior side. The capture region may be sized to receive at least a portion of a native posterior leaflet in an elongated state when the frame is deployed.
