Mitral valve aneurysm after infective endocarditis in the billowing mitral leaflet syndrome.

ABSTRACT

Mitral valve aneurysm is an uncommon complication of infective endocarditis. This report describes a patient with severe regurgitation due to perforations in a mitral aneurysm who required mitral valve replacement 9 years after a staphylococcal infection was superimposed on a billowing mitral leaflet. The unusual auscultatory signs and angiographic appearance could have led to diagnosis of the aneurysm.
