Mitral Valve Prolapse
Mitral valve prolapse (MVP) is a valvular heart disease characterized by the displacement of an abnormally thickened mitral valve leaflet into the left atrium during systole .
It results from myxomatous degeneration secondary to collagen dissolution resulting in stretching of the leaflets and the chordae tendineae. It is seen in association with aortic disease in Marfan’s and annuloaortic ectasia as well as the Ehlos Danlos syndrome.
Structurally collagen dissolution leads to excess mucopolysaccharides in the middle spongiosa layer of the mitral valve leaflets.
Functionally there may be a mitral regurgitation.
Clinically most patients are asymptomatic. Some patients develop supraventricular arrhythmias, palpitations, mitral regurgitation, bacterial endocarditis, and sudden death.
Diagnosis is made by echocardiography.
Treatment is usually reassurance in most cases.
