Claim:
A mitral annuloplasty ring for implantation in a mitral valve annulus having an anterior aspect and a posterior aspect, the annuloplasty ring comprising: a continuous ring body having an anterior portion adapted to be implanted on the anterior aspect of the mitral valve annulus, a posterior portion opposite the anterior portion and adapted to be implanted on the posterior aspect of the mitral valve annulus, right and left sides between the anterior and posterior portions with transition segments between the sides and the anterior and posterior portions; wherein the ring body is oriented about a central axis having an upward direction and a downward direction, the downward direction corresponding to the direction of blood flow through the mitral valve annulus, the ring having in plan view perpendicular to the central axis a major axis and a minor axis and substantially a D-shape with the posterior portion being more convex than the anterior portion; wherein the anterior portion has an upward bow, and, wherein the posterior portion has an upward bow that rises to approximately the same height as the anterior portion such that the ring body defines a three-dimensional surface drawn across the open middle of the ring that is saddle-shaped.
