Abstract
Embodiments of the present disclosure are directed to prosthetic valves and methods of use thereof. In one implementation, a prosthetic valve for implantation within a native mitral valve may be provided. The prosthetic valve may include an annular valve body having an atrial end, a ventricular end, and an intermediate portion between the atrial end and the ventricular end. Atrial anchoring arms and ventricular anchoring legs may extend from the intermediate portion of the valve body. At least one atrial anchoring arm may extend radially outward beyond a terminal end of at least one ventricular anchoring leg. The atrial arms and the ventricular legs may be devoid of lateral interconnections therebetween beyond locations of connection to the intermediate portion. At least one atrial anchoring arm may extend in the generally radially outward direction from a single location of connection to the intermediate portion of the valve body.
