Perforation of the anterior mitral leaflet caused by aortic valve endocarditis: diagnosis by two-dimensional, transesophageal echocardiography and color flow Doppler.
Perforation of the mitral valve as a result of aortic valve endocarditis is rare. Recognition of such abnormality is very important before surgical intervention. Diagnosis is very difficult by either invasive or noninvasive techniques. This report stresses the role of echocardiography in evaluating this rare abnormality. Perforation of the anterior mitral valve leaflet developed in our patient as a complication of aortic valve endocarditis. The perforation was suggested by the surface echocardiogram (as an interruption of the leaflet continuity) and by the color flow Doppler (which suggested turbulent flow at the area of suspected interruption). The perforation was confirmed during surgery by transesophageal echocardiography and alerted the surgeon to repair, rather than replace, the valve.
