1. A method of implanting a prosthetic heart valve assembly, comprising:
inserting a prosthetic heart valve assembly in a compressed state into a heart, the heart valve assembly comprising a self-expandable stent having a flared upper portion, a lower portion, and an intermediate portion extending from the upper portion to the lower portion, wherein the stent tapers from the upper portion toward the lower portion, the heart valve assembly further comprising hooks extending from an outer surface of the stent, a valve portion positioned within a passageway in the stent, and an elongate anchoring member extending from the lower portion of the stent;
advancing the heart valve assembly from a distal end of a sheath for allowing the stent to radially expand from the compressed state to a functional size in a native valve of the heart such that the flared upper portion is deployed in an atrium of the heart and the intermediate portion of the stent is positioned within an annulus of a native heart valve and the hooks extend upwardly toward the flared upper portion and engage native leaflet tissue; and
attaching the elongate anchoring member to a wall of a ventricle;
wherein the flared upper portion contacts a supra-annular surface of the native heart valve for preventing downward migration of the prosthetic heart valve assembly toward the ventricle and the hooks and the elongate anchoring member prevent upward migration of the prosthetic heart valve assembly toward the atrium.
