Claim:
1. A valve prosthesis for replacing an atrioventricular valve of a heart, the prosthesis comprising: a ring-shaped body, to which valvular cusps are attached wherein the ring-shaped body is adapted to be inserted into a valve annulus of the heart, and at least one anchoring element that is non-rotatably affixed to the ring-shaped body and that is configured to protrude in the direction of the ventricle which is a direction pointing away from an atrial side of the ring-shaped body, wherein the at least one anchoring element is adapted to be anchored in chordae, papillary muscles or cusps of the atrioventricular valve upon rotation of said ring-shaped body in a direction of rotation around an axis thereof wherein: the at least one anchoring element comprises an axial component that extends an axial distance from said ring-shaped body and is configured to extend in the direction of the ventricle and a curved component extending circumferentially and being bent around the axis of the ring-shaped body from the axial component such that the curved component is configured to engage with valve chordae upon said rotation, and wherein, in the closed state of the valve, the at least one anchoring element is adapted to transfer essentially axial forces into chordae of the heart.
