Annuloplasty rings and methods for inserting annuloplasty rings are herein disclosed. The annuloplasty ring has a ring shell and a plurality of anchoring fasteners for anchoring the ring shell to adjacent heart tissue. To maintain the shape of the annuloplasty ring upon attachment of the ring to the patients heart, a hardening polymer is inserted into the ring shell, which is permitted to cure, thereby providing support for the annuloplasty ring and the patients heart valve.
