Abstract
The invention is an annuloplasty ring, and associated methods therefore, configured to reshape a native heart valve annulus to correct heart valve function, and also configured to be reshaped into a generally circular form in order to receive and/or support a prosthetic heart valve. The annuloplasty ring may be configured to have a generally D-shaped configuration when initially implanted to correct native valve function, but to assume a generally circular form when subjected to an outward force such as that provided by a dilation balloon.
