System and method for cardiac valve repair and replacement

A prosthetic mitral valve comprising:

• an anchor assembly comprising a ventricular anchor, a central portion, and an atrial anchor, the anchor assembly configured to self-expand from a collapsed configuration to an expanded configuration, the anchor assembly configured to foreshorten when self-expanding from the collapsed configuration to the expanded configuration such that the prosthetic mitral valve obtains an expanded length L that is less than a length of the prosthetic mitral valve in the collapsed configuration, further wherein the ventricular anchor and the atrial anchor are configured to flare outward relative to the central portion when self-expanding from the collapsed configuration to the expanded configuration such that the prosthetic mitral valve obtains an outermost diameter D that is greater than an outermost diameter of the prosthetic mitral valve in the collapsed configuration;
• a plurality of replacement leaflets secured to the anchor assembly;
• and
• a plurality of struts attached to the anchor assembly and extending distally past the ventricular anchor when the anchor assembly is in the expanded configuration, the plurality of leaflets secured to the anchor assembly with the plurality of struts;
• wherein a ratio of D to L is greater than or equal to 2.

A prosthetic mitral valve comprising:

• an anchor assembly comprising a ventricular anchor, a central portion, and an atrial anchor, wherein the central portion has a segment that extends substantially parallel to a longitudinal axis of the prosthetic mitral valve, the anchor assembly configured to self-expand from a collapsed configuration to an expanded configuration, the anchor assembly configured to foreshorten when self-expanding from the collapsed configuration to the expanded configuration such that the prosthetic mitral valve obtains an expanded length L that is less than a length of the prosthetic mitral valve in the collapsed configuration, further wherein the ventricular anchor and the atrial anchor are configured to flare outward relative to the central portion when self-expanding from the collapsed configuration to the expanded configuration such that the prosthetic mitral valve obtains an outermost diameter D that is greater than an outermost diameter of the prosthetic mitral valve in the collapsed configuration;
• and
• a plurality of replacement leaflets secured to the anchor assembly;
• wherein a ratio of D to L is greater than or equal to 2.

• a plurality of replacement leaflets secured to the anchor assembly;
• and
• a plurality of retention hooks attached to the anchor assembly, wherein the plurality of retention hooks are curved such that, when the anchor assembly is in the collapsed configuration, the hooks flatten and collapse, and when the anchor assembly is in the expanded configuration, the hooks extend outwards;
• and
• wherein a ratio of D to L is greater than or equal to 2.
