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 and which is adapted to be inserted into a valve annulus of the heart,a plurality of anchoring elements connected to the ring-shaped body at its ventricular side and extending at least partially radially outside and essentially parallel to the outer wall of the ring-shaped body, anda plurality of anchoring elements connected to the ring-shaped body at its atrial side and extending outside and essentially parallel to the outer wall of the ring-shaped bodyan axial distance between ends of the plurality of ventricular side anchoring elements and ends of the plurality of atrial side anchoring elements is so dimensioned that it corresponds approximately to the axial thickness of said annulus to produce a clamping action between the anchoring elements and the mitral valve leaflets or chordaewherein the anchoring elements extend at the ventricular side of the ring-shaped body over at least half of the axial length (LR) of the ring-shaped body.

Abstract
A prosthetic valve for replacing an atrioventricular heart valve comprises an annular body (2) on which valvular cusps are fastened and which is adapted to be inserted into a valve annulus (18) of the heart (20). The annular body has a plurality of anchor elements which are connected thereto on the ventricle side and optionally other anchor elements which are connected to the annular body on the atrium side. Said anchor elements extend radially outside the annular body and substantially parallel to its outer wall.

9. A valve prosthesis for replacing an atrioventricular valve of a heart, the prosthesis comprising:
-
a ring-shaped body to which valvular cusps are attached and which is adapted to be inserted into a valve annulus of the heart, a plurality of anchoring elements connected to the ring-shaped body at its ventricular side and extending at least partially radially outside and essentially parallel to the outer wall of the ring-shaped body, and a plurality of anchoring elements connected to the ring-shaped body at its atrial side and extending outside and essentially parallel to the outer wall of the ring-shaped body an axial distance between ends of the plurality of ventricular side anchoring elements and ends of the plurality of atrial side anchoring elements is so dimensioned that it corresponds approximately to the axial thickness of said annulus to produce a clamping action between the anchoring elements and the mitral valve leaflets or chordae wherein the ends of the anchoring elements have a ring-shape or partial ring-shape.
