1. A method for use with a prosthetic valve that is configured to be deployed within a native atrio-ventricular valve of a heart of a mammalian subject, the native atrio-ventricular valve including a valve annulus, valve leaflets, chords, and papillary muscles, the method comprising:

  • placing a valve frame within the subject'"'"'s heart, the valve frame including;

    a valve frame body that is configured to support the prosthetic valve within the native atrio-ventricular valve, and that includes an atrial portion and a ventricular portion, andat least one arm that is configured to extend from the ventricular portion of the valve frame;

    subsequently, deploying the at least one arm among the chords of the native atrio-ventricular valve;

    subsequently, rotating at least a portion of the valve frame, in a direction in which an interior of the arm faces, such as to cause the arm to (a) pull the native atrio-ventricular valve radially inward toward the valve frame, and (b) twist the native atrio-ventricular valve around the valve frame, by recruiting and deflecting at least a portion of the chords; and

    subsequently, causing the frame body of the valve frame to radially expand, such as to trap the native valve leaflets in a partially closed and twisted configuration, to thereby at least partially seal a space between the native atrio-ventricular valve and the prosthetic valve.
