1. A method comprising:
- delivering to a native annulus of an atrioventricular valve of a heart a prosthetic valve via an opening in a wall of the ventricle of the heart, the prosthetic heart valve having a self-expanding body having a proximal end and a distal end, a valve disposed in the body, anda plurality of self-expanding atrial anchoring elements distributed circumferentially about, and extending radially outwardly from, the proximal end of the body, anda plurality of anchoring sutures, each anchoring suture having a first end and a second end, the first end being attached to the distal end of the body, the delivering including disposing the atrial anchoring elements on an atrium side of the native annulus and the anchoring sutures through the opening;
allowing the body to self-expand into engagement with the native annulus; and
fixing the plurality of anchoring sutures to the wall of the heart.
