Claim 0:
1. A low-profile prosthetic valve for treating a native valve in a patient, said valve comprising:
a radially expandable frame having an expanded configuration, a collapsed configuration, an atrial end and a ventricular end,
wherein in the collapsed configuration the expandable frame is sized and shaped for minimally invasive delivery to the native valve,
wherein in the expanded configuration the expandable frame is configured to engage the native valve,
wherein the atrial end forms a flared shape in the expanded configuration, and configured to engage an atrial surface of the native valve,
wherein the flared shape flares downward toward a ventricle of the native valve when initially expanded followed by inversion of the flared shape to form a tapered shape tapering toward the ventricle and flaring toward an atrium of the native valve when fully expanded;
a plurality of prosthetic valve leaflets having a free end and an opposite end coupled to an inner portion of the expandable frame, an open configuration and closed configuration; and
a plurality of ventricular wings on the ventricular end,
wherein in the open configuration the free ends of the plurality of prosthetic valve leaflets are disposed away from one another relative thereby forming an aperture through which fluid flows in an antegrade direction,
wherein in the closed configuration the free ends are disposed closer together than in the open configuration thereby substantially closing the aperture and preventing the fluid from flowing therethrough in a retrograde direction,
wherein in the plurality of ventricular wings has an expanded configuration and a collapsed configuration,
wherein in the collapsed configuration the plurality of ventricular wings is substantially parallel with a longitudinal axis of the prosthetic valve, and
wherein the expanded configuration the plurality of ventricular wings extends radially outward from the longitudinal axis to form a flange configured to engage a ventricular surface of the native valve.
