Definition: excessive retrograde movement of one or both mitral valve leaflets into the left atrium during left ventricular systole, often allowing mitral regurgitation; responsible for the click-murmur of Barlow syndrome, and rarely may be due to rheumatic carditis, a connective tissue disorder such as Marfan syndrome, or ruptured chorda tendinea (“flail mitral leaflet”).
