Mitral valve annuloplasty double by the year 2030. Every year, 300,000 people worldwide undergo open heart surgery for mitral valve repair, 44,000 people in the US alone. Since it was initially established 40 years ago by Professor Alain Carpentier, mitral valve annuloplasty has been continuously improved and is considered the gold standard for the treatment of most etiologies of mitral valve dysfunction today. The goal of mitral valve annuloplasty is to regain mitral valve competence by restoring the physiological form and function of the normal mitral valve apparatus. Under normal conditions the mitral valve undergoes significant dynamic changes in shape and size throughout
Mitral valve prolapse Two- and three-dimensional echocardiography are particularly valuable as they allow visualization of the mitral leaflets relative to the mitral annulus. This allows measurement of the leaflet thickness and their displacement relative to the annulus. Thickening of the mitral leaflets >5 mm and leaflet displacement >2 mm indicates classic mitral valve prolapse. Prolapsed mitral valves are classified into several subtypes, based on leaflet thickness, type of connection to the mitral annulus, and concavity. Subtypes can be described as classic, nonclassic, symmetric, asymmetric, flail, or non-flail. All measurements below refer to adult patients; applying them to children may be misleading.
