Abstract
Apparatus and methods are described including a prosthetic valve support (40) configured to be placed at a patient's native atrioventricular valve annulus. The valve support defines an annular element (44) that defines an inner cross-sectional area thereof. An expandable prosthetic valve (80) is placed into the patient's ventricle, the prosthetic valve including an expandable frame (79) and prosthetic valve leaflets (82) coupled to the frame. When the frame is in a non-constrained state thereof, a cross-sectional area of the frame, along at least a given portion L of the frame's length, is greater than the cross-sectional area defined by the annular element. The prosthetic valve is couplable to the prosthetic valve support at any location along the portion, by the frame being expanded when the location along the portion is aligned with the annular element. Other applications are also described.
