Abstract
A method comprises implanting an aortic ring externally on the outer surface and around the aortic root to form a closed-perimeter flexible structure only around the subvalvular region externally of the aortic root, generally adjacent the nadir portion of the valve annulus and below the attachment points of the coronary arteries; and constraining the aortic root with the closed-perimeter structure to an anatomically representative geometry that improves coaptation of the leaflet free margins in the diastolic phase of the cardiac cycle.
