1. Apparatus, comprising:
- one or more valve support guide members configured to be delivered to one or more commissures of a native atrioventricular valve of a patient;
a prosthetic valve support configured to be advanced toward the native valve along the one or more valve support guide members and placed at the native valve;
a prosthetic valve configured to be coupled to the valve support; and
one or more sealing elements configured to facilitate sealing of an interface between the prosthetic valve support and the native valve.

Abstract
Apparatus and methods are described, including one or more valve support guide members that are delivered to one or more commissures of a native atrioventricular valve of a patient. A prosthetic valve support is advanced toward the native valve along the one or more valve support guide members and placed at the native valve. A prosthetic valve is coupled to the valve support. One or more sealing elements facilitate sealing of an interface between the prosthetic valve support and the native valve. Other applications are also described.

23. Apparatus, comprising:
-
a prosthetic valve support configured to be advanced toward a native atrioventricular valve of a patient and placed at the native valve; a prosthetic valve configured to be coupled to the valve support, the prosthetic valve being shaped so as to define first and second sets of one or more protrusions, each set of protrusions configured to ensnare a respective native leaflet of the native valve of the patient, the first set of protrusions being disposed within a first circumferential arc with respect to a longitudinal axis of the prosthetic valve, on a first side of a distal end of the prosthetic valve, the second set of protrusions being disposed within a second circumferential arc with respect to the longitudinal axis of the prosthetic valve, on a second side of the distal end of the prosthetic valve, the first and second sets being disposed so as to provide first and second gaps therebetween at the distal end of the prosthetic valve, at least one of the gaps having a circumferential arc of at least 20 degrees; and one or more valve guide members configured to be delivered to one or more commissures of the native valve, and to guide the valve such that the first and second circumferential arcs are aligned with respective leaflets of the native valve and such that the first and second gaps are aligned with respective commissures of the native valve. - View Dependent Claims (24, 25, 26, 27, 28)

29. A method, comprising:
-
determining an area defined by an annulus of a native atrioventricular valve of a patient; selecting a prosthetic valve to be placed in the native valve by determining that the valve defines a cross-sectional area that is less than 90% of the area defined by the annulus; and deploying the prosthetic valve at the native valve, the selecting of the prosthetic valve facilitating sealing of the native valve with respect to the prosthetic valve by facilitating closing of leaflets of the native valve around the prosthetic valve, upon deployment of the prosthetic valve. - View Dependent Claims (30, 31, 32, 33, 34)
