Abstract
A valve prosthesis is adapted to operate in conjunction with native heart valve leaflets. The prosthesis includes an annulus and a skirt extending from the annulus. The skirt may be configured to be positioned through a native heart valve annulus, and the skirt may be movable between an open configuration permitting blood flow through the skirt and a closed configuration blocking blood flow through the skirt in cooperation with opening and closing of the native heart valve leaflets.

A prosthetic cardiac valve support device comprising:
- an annular support element configured for positioning at or near a native heart valve annulus;
- at least two valve support extensions shaped to extend through commissures of the native heart valve for supporting a flexible valve;
- and
- at least two anchoring extensions:
- attached at one end to said annular support element, and extending in an opposite direction towards an unattached end;
- in a form of hooks shaped for anchoring said annular support element to tissue;
- all of the anchoring extensions being adapted to extend through commissures of a native heart valve without interfering with movement of native heart valve leaflets;
- and
- the anchoring extensions shaped to prevent said annular support element from shifting upstream relative to the native heart valve annulus.
