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 annuioplasty ring which compresses the lateral dimension of the valve. Other specifically configured annuioplasty rings can also be utilized. The sizes of the patch and ring are selected to provide a sufficient advancement of the leaflet to restore the surface of coaptation. |
