Japanese Patent JP7006940

B2

An aspect of the disclosure provides a prosthetic heart valve for implantation in a native mitral valve of a patient, said heart valve comprising: a radially expandable anchor frame having an expanded configuration and a collapsed configuration; and a prosthetic valve coupled to the anchor frame, the prosthetic valve comprising a plurality of prosthetic valve leaflets each having a free end and a fixed end, wherein the fixed end is coupled to the anchor frame, and wherein the free ends of the plurality of prosthetic valve leaflets have an open configuration and a closed configuration, in the open configuration the free ends are disposed away from one another to allow antegrade blood flow therethrough, and in the closed configuration the free ends are disposed adjacent one another to substantially prevent retrograde blood flow therethrough, and wherein the plurality of prosthetic valve leaflets comprise an anterior prosthetic leaflet sized to span the entire width of the native anterior leaflet, and wherein in systole, the anterior prosthetic leaflet deflects away from the left ventricular outflow tract to provide a clear unobstructed outflow path.
