Mitral valve prolapse

Mitral valve prolapse (MVP) is often defined as systolic bowing of the mitral leaflet more than 2 mm beyond the annular plane into the atrium 1. It is a common cause of mitral regurgitation (considered most frequent cause of severe non-ischaemic mitral regurgitation 2).

It may affect up to 2-3% of the general population 3

Mitral leaflet bowing is caused by rupture or elongation of the chordae tendineae (often due to myxomatous degeneration). The middle scallop of the posterior leaflet (P2 segment) is most often affected.

It is usually repaired surgically.
