Abstract
Prosthetic valves and methods of implanting prosthetic valves may be provided, including a prosthetic valve for implantation within a native heart valve. The prosthetic valve may include an annular valve body, a plurality of atrial anchoring arms, and a plurality of ventricular anchoring legs. The arms and legs may extend radially outward from the annular valve body and may each include a native valve tissue engaging portion. The arms may be angularly offset from the legs, with the tissue engaging portion of each arm and each leg arranged such that when the arms and legs are positioned on opposing sides of native heart valve tissue, the native heart valve tissue may assume a serpentine arrangement between the arms and the legs.
