Mitral valve prolapse of mitral valve prolapse in Framingham, MA was estimated at 2.4%. There was a near-even split between classic and nonclassic MVP, with no significant age or sex discrimination. MVP is observed in 7% of autopsies in the United States. The term "mitral valve prolapse" was coined by J. Michael Criley in 1966 and gained acceptance over the other descriptor of "billowing" of the mitral valve, as described by John Brereton Barlow. Mitral valve prolapse 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
Mitral valve prolapse with palpitations, atypical chest pain, dyspnea on exertion, low body mass index, and electrocardiogram abnormalities in the setting of anxiety, syncope, low blood pressure, Migraine-Like Headache, orthostatic hypotension, lightheadedness, and other signs suggestive of autonomic nervous system dysfunction (dysautonomia). Mitral valve prolapse is frequently associated with mild mitral regurgitation, where blood aberrantly flows from the left ventricle into the left atrium during systole. In the United States, MVP is the most common cause of severe, non-ischemic mitral regurgitation. This is occasionally due to rupture of the chordae tendineae that support the mitral valve. MVP may occur with greater frequency in
