Abstract
A heart valve prosthesis has a suture ring with a core for form-coupling with the stent of the prosthesis so that the suture ring and the stent are held securely together axially, while the core can rotate relative to the stent. The suture ring has a covering which cooperates with the surface of the stent and is in contact therewith. The degree of contact determines the resistance to relative rotation of the ring and the stent.
