Mitral valve repair surgery is much more technically demanding and may involve higher risk. Occasionally, the mitral valve is abnormal from birth (congenital). More often the mitral valve becomes abnormal with age (degenerative) or as a result of rheumatic fever. In rare instances the mitral valve can be destroyed by infection or a bacterial endocarditis. Mitral regurgitation may also occur as a result of ischemic heart disease (coronary artery disease) or non-ischemic heart disease (dilated cardiomyopathy). In 1923 Dr. Elliott Cutler of the Peter Bent Brigham Hospital performed the world’s first successful heart valve surgery – a mitral valve "repair". The patient was
Mitral valve annuloplasty are believed to be key to optimize leaflet coaptation and to minimize tissue stresses. The challenge of mitral valve annuloplasty is to improve the diseased and distorted shape of the mitral valve and to reestablish the physiological configuration, while preserving normal annular dynamics. Today, cardiac surgeons can select from a variety of annuloplasty devices, flexible, semi-rigid, or rigid, incomplete or complete, planar or saddle-shaped, adjustable and non-adjustable. While the general goal of all devices is the same, namely to increase leaflet coaptation and to support the posterior annulus against dilation, flexible bands are designed to maintain the three-dimensional contour of
