Abstract: Apparatus and methods are described including placing a valve frame within a subject's heart. The valve frame is configured to support the prosthetic valve within the native atrio-ventricular valve and includes a valve frame body having atrial and ventricular parts and at least one arm that is configured to extend from the ventricular part. The arm is deployed among chords of the native atrio-ventricular valve and is rotated, such as to pull the native atrio-ventricular valve radially inward toward the valve frame and twist the native atrio-ventricular valve around the valve frame, by recruiting and deflecting at least a portion of the chords. The frame body of the valve frame traps the native valve leaflets in a partially closed and twisted configuration by radially expanding, to thereby at least partially seal a space between the native atrio-ventricular valve and the prosthetic valve. Other applications are also described.
