Abstract
Apparatus and methods are described for use with a native tricuspid valve of a heart of a subject. A valve frame includes a valve-frame body that is configured to support prosthetic valve leaflets within the native tricuspid valve. Chord-recruiting arms are configured to extend from the valve-frame body at circumferential regions corresponding to the anterior leaflet and the posterior leaflet of the native tricuspid valve. An anchoring arm is configured to extend from the valve-frame body at a circumferential region corresponding to the septal leaflet of the native tricuspid valve, the anchoring arm being longer than each of the chord-recruiting arms. Other applications are also described.
