Mitral valve reconstruction offers patients an important alternative to the traditional method for treating severe mitral regurgitation—mitral valve replacement. Over the last 15 years, surgical techniques have evolved for treating mitral regurgitation occurring from various anatomic mechanisms—annular dilatation, abnormal leaflet motion due to a variety of causes, or leaflet perforation. Currently, over 90% of regurgitant mitral valves of varying etiologies are amenable to nonreplacement therapy by reconstruction, with good intermediate- and long-term results. Reconstruction obviates the need for long-term anticoagulation, and thus, there has evolved a trend toward reconstruction earlier in the course of this disease, before fixed atrial fibrillation and ventricular dilatation occur.
