Zusammenfassung:A system for reshaping a valve annulus includes an elongate template having a length along a longitudinal axis and at least one concavity in a generally lateral direction along said length. The pre-shaped template is positioned against at least a region of an inner peripheral wall of the valve annulus, and at least one anchor on the template is advanced into a lateral wall of the valve annulus to reposition at least one segment of the region of the inner peripheral wall of the valve annulus into said concavity. In this way, a peripheral length of the valve annulus can be foreshortened and/or reshaped to improve coaptation of the valve leaflets and/or to eliminate or decrease regurgitation of a valve.
