Transcatheter mitral valve prosthesis
First Claim
1. A method of anchoring a prosthetic valve in a patient'"'"'s heart having a native mitral valve, said method comprising:
- delivering a prosthetic cardiac mitral valve in a collapsed configuration to the patient'"'"'s heart, wherein the prosthetic cardiac mitral valve comprises an anchor having a first anterior trigonal anchoring tab disposed on an anterior portion of the prosthetic cardiac mitral valve;
radially expanding the anchor from the collapsed configuration to an expanded configuration to engage the native mitral valve;
anchoring the prosthetic cardiac mitral valve to the native mitral valve, wherein anchoring the prosthetic cardiac mitral valve comprises expanding the first anterior trigonal anchoring tab radially outward and engaging the first anterior trigonal anchoring tab against a first fibrous trigone of the native mitral valve; and
disposing adjacent chordae tendineae between the first anterior trigonal anchoring tab and an anterior surface of the anchor.

Abstract
A prosthetic cardiac valve comprises an anchor having an atrial skirt, an annular region, and a ventricular skirt. The prosthetic valve also has a plurality of prosthetic valve leaflets each having a first end and a free end. The first end is coupled with the anchor and the free end is opposite the first end. The prosthetic cardiac valve has an open configuration in which the free ends of the prosthetic valve leaflets are disposed away from one another to allow antegrade blood flow therepast, and a closed configuration in which the free ends of the prosthetic valve leaflets engage one another and substantially prevent retrograde blood flow therepast. The anchor has a collapsed configuration for delivery to the heart and an expanded configuration for anchoring the prosthetic cardiac valve to a patient'"'"'s heart.
