Nonreplacement operations for mitral valve regurgitation.
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.
