Reparative surgery for degenerative mitral valve regurgitation

Reparative surgery for degenerative mitral valve regurgitation or insufficiency has been the subject of countless articles in the literature over the past five decades. During this period, a wealth of experience has contributed to greater understanding of mitral valve anatomy and pathophysiology. Excellent surgical techniques for the treatment of mitral regurgitation have been developed and are undergoing further refinement. With the efforts of the pioneers, standard surgical techniques, strategies, and guidelines have been well established. These achievements significantly prolong the life-expectancy of patients, provide excellent long-term durability of the repaired valve, and reduce the risk of endocarditis. Mitral valve repair for degenerative mitral regurgitation also contributes to reduced risk of thromboembolic events and the need for life-long anticoagulation after mitral valve replacement.
