Abstract: A cardiac valve prosthesis includes a rotatably mounted, disc-shaped valve flap which is provided with two outwardly oriented, convex attachments disposed opposite one another at the points of intersection of a secant with the edge of the disc. The valve also includes an annular body having on its interior wall first recesses for receiving the convex attachments to thus form a bearing socket for the valve flap. At its interior wall, the annular body is provided with second recesses which communicate with the first recesses to form a passage for the convex attachments during insertion thereof into the first recesses.
