A heart valve prosthesis (10) includes a molded body (12) and a plurality of leaflets (18). Each leaflet (18) includes a free margin (22) having opposite ends and a mid-point. The opposite ends are attached to a peripheral portion of the valve. Each free margin (22) is adjacent each other free margin (22) to form a natural-state non-uniform gap (24) therebetween. The gap (24) has a maximized width adjacent the mid-point of each leaflet (18). Each free margin (22) is scalloped to form a peak (36) at the opposite ends and a mid-point peak (40) between the opposite ends. Each peak is substantially the same height above the base.

Chaque feuillet (18) comporte un bord libre (22) ayant des extrémités opposées et un point central. Les extrémités opposées sont attachées à une partie périphérique de la valvule. Chaque bord libre (22) est adjacent à chaque autre bord libre (22) pour former un espace intermédiaire (24) non uniforme à l'état naturel. L'espace (24) a une profondeur maximisée juste à côté du point central de chaque feuillet (18). Chaque bord libre (22) est festonné pour former une crête (36) aux extrémités opposées et une crête (40) de point central située entre les extrémités opposées. La hauteur de chaque crête est sensiblement identique au-dessus de la base.
