Abstract

Apparatus and methods are described including a prosthetic atrioventricular valve (10) for coupling to a native atrioventricular valve (12). The prosthetic valve includes a support frame (20) and a covering (22), which at least partially covers the support frame. The support frame and the covering are shaped so as to define a downstream skirt (24). A plurality of prosthetic leaflets (40) are coupled to at least one element selected from the group consisting of the support frame and the covering. An elongated anchoring member (152) is positioned around the downstream skirt in a subvalvular space (150), such that the anchoring member presses native leaflets (30) of the native valve against the downstream skirt, thereby anchoring the prosthetic valve to the native valve. Other applications are also described.
