Mitral valve prolapse(MVP) (a.k.a. floppy mitral valve syndrome, systolic click murmur syndrome or billowing mitral leaflet) is a valvular heart disease characterized by the displacement of an abnormally thickened mitral valveleaflet into the left atrium during systole. It is the primary form of myxomatous degeneration of the valve. There are various types of MVP, broadly classified as classic and nonclassic. In its nonclassic form, MVP carries a low risk ofcomplications and often can be kept minimal by dietary attention. In severe cases of classic MVP, complications includemitral regurgitation, infective endocarditis, congestive heart failure, and, in rare circumstances, cardiac arrest.
The diagnosis of MVP depends upon echocardiography, which uses ultrasound to visualize the mitral valve. The prevalence of MVP is estimated at 2-3% of the population.
The condition was first described by John Brereton Barlow in 1966. In consequence, it may also be referred to as Barlow's syndrome, and was subsequently termed mitral valve prolapse by J. Michael Criley.
