Abstract
An annuloplasty ring includes an anterior portion, and a posterior portion which defines a central portion and two lateral portions. The ring is adapted for optional removal of the anterior and/or the central posterior portion. Removal of the central posterior portion reduces the gradient across the ring providing enhanced valve performance. Removal of the anterior portion preserves normal annular movement. The lateral posterior portions are stiffer than the construction at the anterior and central posterior portions. If the ring is used with the central posterior portion intact, the gradient is also reduced. The ring includes indicia of multiple sets of suture markings, each set identifying a plurality of suture locations about the perimeter of the ring which are adapted to cinch the annulus a predetermined amount about the ring. A single ring may be used to cinch the annulus in accord with relatively different degrees of desired valve area reduction.
