Claim:
Heart valve prosthesis comprising: a ring member for attachment to a valve annulus; and a constriction system comprising anchoring pins for penetrating into the valve annulus, wherein the anchoring pins have a straight first position and a second position; wherein, in the first position, the anchoring pins extend in an axial direction; wherein the anchoring pins are arranged around the circumference of the ring member and are adapted to move, after the anchoring pins have fully penetrated into the valve annulus from the first position in a radially inward direction with respect to the ring member, to the second position, to press the annulus correspondingly in the radially inward direction; wherein the ring member comprises a lower flange which is bendable from a straight axial position to a radially outward position with respect to the ring member, and an upper flange having a radial outwardly extending position with respect to the ring member, and wherein, when the lower flange is in the radially outward position, the anchoring pins are arranged between the upper and lower flange.
