Abstract: A method for delivering a prosthetic valve to a patient's heart having a native valve with a plurality of valve leaflets includes providing a delivery device with a prosthetic valve, advancing the delivery device toward the native valve, and expanding a portion of the prosthetic valve to form a flanged region that is upstream of the valve leaflets. One or more tabs on the prosthetic valve are released so that they expand outward to a position that is transverse to the longitudinal axis of the prosthetic valve. The position of the prosthetic valve is adjusted relative to the valve leaflets and rapid pacing is applied to the patient's heart so that the valve leaflets move inward toward the prosthetic valve or the delivery device. The tabs are further released to allow the tabs to move into their final positions.

Abstract: A prosthetic mitral valve may be anchored in a native mitral valve. The prosthetic mitral valve preferably has a large anterior prosthetic leaflet that spans the entire width of the native anterior leaflet and the anterior prosthetic leaflet moves away from left ventricular outflow tract during systole to create a clear unobstructed outflow path.

Abstract: A low-profile prosthetic valve for treating a native valve includes a radially expandable frame having an expanded configuration and a collapsed configuration. The atrial end of the prosthetic valve forms a flared shape that engages an atrial surface of the native valve. The flare 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 the atrium of the native valve when fully expanded. The prosthetic valve also has a plurality of prosthetic valve leaflets that open and close to control fluid flow through the prosthetic valve.
