Abstract
Described herein are methods of remodeling the base of a ventricle. In particular, methods of remodeling a valve annulus by forming a new fibrous annulus are described. These methods may result in a remodeled annulus that corrects valve leaflet function without substantially inhibiting the mobility of the leaflet. The methods of remodeling the base of the ventricle include the steps of securing a plurality of anchors to the valve annulus beneath one or more leaflets of the valve, constricting the valve annulus by cinching a tether connecting the anchors, and securing the anchors in the cinched conformation to allow the growth of fibrous tissue. The annulus may be cinched (e.g., while visualizing the annulus) so that the mobility of the valve leaflets is not significantly restricted. The remodeled annulus is typically constricted to shorten the diameter of the annulus to correct for valve dysfunction (e.g., regurgitation).
