1. A method of treating a disorder of a native mitral valve in a heart, comprising:
inserting a delivery device with a mitral valve prosthesis into a left ventricle of the heart;
advancing the delivery device into the left ventricle to position the mitral valve prosthesis within the native mitral valve, wherein the mitral valve prosthesis comprises a prosthetic valve and a frame having an expandable inflow region, with a cross-sectional diameter larger than an annulus of the native mitral valve, and an expandable outflow region; and
releasing the mitral valve prosthesis from the delivery device to permit the inflow region to expand into apposition with a wall of a left atrium of the heart, and to permit the outflow region to expand into apposition with the annulus of the native mitral valve;
positioning at least one anchor between the outflow region of the mitral valve prosthesis and the heart to tether the mitral valve prosthesis to the heart; and
adjusting tension on the at least one anchor to provide stability to the mitral valve prosthesis
wherein the at least one anchor includes an anchoring element at a first end thereof, the anchoring element being configured in an open state to permit adjustment of the tension on the at least one anchor and in a closed state to attach the at least one anchor to the heart by gripping and holding the heart.
