Abstract:
1. A method of anchoring a prosthetic valve in a patient's heart, said method comprising: providing the prosthetic valve, wherein the prosthetic valve comprises an anchor having an atrial skirt, an annular region, a ventricular skirt, and a plurality of valve leaflets, wherein the ventricular skirt comprises a first trigonal anchoring tab disposed on an anterior portion of the ventricular skirt, wherein the anchor has a collapsed configuration for delivery to the heart and an expanded configuration for anchoring with the heart; positioning the prosthetic valve in the patient's heart; expanding the atrial skirt radially outward so as to lie over a superior surface of the patient's native mitral valve, and anchoring the atrial skirt against a portion of the atrium; radially expanding the annular region of the anchor to conform with and to engage the native mitral valve annulus; anchoring the first trigonal anchoring tab against a first fibrous trigone on a first side of an anterior leaflet of the native mitral valve, such that the anterior leaflet and adjacent chordae tendineae are captured between the trigonal anchoring tab and an anterior surface of the anchor; and radially expanding the ventricular skirt thereby displacing the native mitral valve leaflets radially outward.
