Apparatus, systems, and methods are provided for repairing heart valves through percutaneous transcatheter delivery and fixation of annuloplasty rings to heart valves. An annuloplasty ring (100) includes an outer hollow body member (101) including a plurality of regions. Adjacent regions (102A, 102B) cooperate with one another to change the body member from an elongate insertion geometry to an annular operable geometry. Adjacent regions are coupled by a biasing element (103A, 103B) or a stepped connector to allow expansion to an expanded state and contraction to a contracted state in the annular operable geometry. The annuloplasty ring also includes an internal anchor member located at least partially within the body member and having a plurality of anchors (104) configured to attach the annuloplasty ring to tissue of a heart valve annulus. An angled ring closure lock (106) allows coupling of the ends of an annuloplasty ring at an apex of a D-shape annular operable geometry.
