Mitral valve repair for degenerative mitral valve regurgitation.

In industrialized countries, the most common etiology of mitral regurgitation (MR) is degenerative mitral valve (MV) disease. The natural history of severe degenerative MR is poor. However, its appropriate and timely correction is associated with a life expectancy similar to that of the normal population. Surgical MV repair is the gold-standard treatment. This review will focus on the most recent evidence with a specific emphasis on surgical indications, timing of treatment, contemporary surgical techniques, Heart Teams, and Centers of Excellence. © Indian Association of Cardiovascular-Thoracic Surgeons 2019.
