[Prolapsing echoes in the left ventricular outflow tract and in the left atrium in patients with infective endocarditis. M-mode and cross-sectional echocardiography combination].

In two patients with infective endocarditis and prolapsing echoes in the left ventricular outflow tract (patient with aortic valve involvement) and in the left atrium (patient with mitral valve involvement), easy differentiation between prolapsing vegetation and flail valve leaflet was made possible by means of M-mode and cross-sectional echocardiography.
