An apparatus (10) for helping improve operation of a heart valve includes a generally annular base (12) and a buttress (20) extending generally axially from and inwardly relative to an arc portion of the base (12). When the apparatus (10) is when implanted at an annulus of a heart valve, the buttress (20) thereof provides a surface with which a leaflet of the heart valve may move into and out of engagement for helping control blood flow relative to the apparatus (10) and heart valve.

L'invention concerne un appareil (10) visant à améliorer le fonctionnement d'une valvule cardiaque, qui comprend une base généralement annulaire (12) et un renflement (20) d'extension généralement axiale depuis un arc de la base et vers l'intérieur par rapport à cet arc de la base (12). Lorsque l'appareil (10) est implanté au niveau d'un anneau de valvule cardiaque, le renflement (20) constitue une surface par le biais de laquelle une valve de valvule cardiaque peut s'engager et se dégager, ce qui permet de mieux contrôler le flux sanguin par rapport à l'appareil (10) et à la valvule cardiaque.
