Claim:
1. A method of delivering an implantable prosthetic valve to a patient's heart, the patient's heart having a mitral valve with an anterior leaflet and a posterior leaflet, said method comprising: providing a prosthetic valve, wherein the prosthetic valve comprises an expandable frame having a first end, a second end opposite the first end, a first anterior tab on an anterior portion of the expandable frame, a posterior tab on a posterior portion of the expandable frame, and a ventricular skirt adjacent the first end of the expandable frame, and wherein the prosthetic valve has an expanded configuration for engaging the heart and a collapsed configuration; delivering the prosthetic valve in the collapsed configuration to the patient's heart adjacent the mitral valve; expanding the first anterior tab radially outward such that a tip portion of the first anterior tab engages a first fibrous trigone on a first side of the anterior leaflet of the mitral valve, and wherein the anterior leaflet and adjacent anterior chordae tendineae are disposed between the first anterior tab and an outer anterior surface of the ventricular skirt; after radially expanding the first anterior tab, radially expanding the posterior tab outward such that the posterior leaflet of the mitral valve and adjacent posterior chordae tendinae are disposed between the posterior tab and an outer posterior surface of the ventricular skirt; after radially expanding the posterior tab, radially expanding the ventricular skirt outward thereby engaging the anterior and posterior leaflets, wherein the anterior leaflet and the adjacent anterior chordae tendinae are captured between the first anterior tab and the outer anterior surface of the ventricular skirt, and wherein the posterior leaflet and the adjacent posterior chordae tendinae are captured between the posterior tab and the posterior outer surface of the ventricular skirt.
