<p>A system and process for correction of regurgitation of heart valves. With mitral valves in particular, the anterior leaflet is advanced through use of a D- plasty patch and a narrow annuloplasty ring which compresses the lateral dimension of the valve. The sizes of the patch and ring are selected to provide a sufficient advancement of the leaflet to restore the surface of coaptation.</p> |
