A method for improving leaflet prolapse and/or valve regurgitation associated with a heart valve involves delivering a catheter into a ventricle of a heart, attaching a cord to a first papillary muscle disposed in the ventricle, the first papillary muscle being connected to a first leaflet of an atrioventricular heart valve, attaching the cord to a second papillary muscle, the second papillary muscle being connected to a second leaflet of the heart valve, secure first and second portions of the cord in a fixed relative position to form a loop attached to both the first and second papillary muscles, and releasing the cord from the catheter.
