Abstract
Apparatus and methods are described including placing a valve frame within a subject's heart. The valve frame includes a valve frame body that is configured to support the prosthetic valve within the native atrio-ventricular valve, and at least one arm that is configured to extend from a ventricular portion of the valve frame. The at least one arm is deployed among chords of the native atrio-ventricular valve. Subsequently, at least a portion of the valve frame is rotated in a direction in which an interior of the arm faces, such as to modify shapes of the native valve leaflets and the ventricular structures, by recruiting and deflecting at least a portion of the chords. The frame body of the valve frame is then radially expanded, such as to hold the native valve leaflets and the ventricular structures at least partially in the modified shapes. Other applications are also described.
