title: Systolic anterior motion of the mitral valve. An unusual echocardiographic feature of mitral valve endocarditis.
abstract: An unusual M-mode echocardiographic feature of mitral valve endocarditis is described: systolic anterior motion of the mitral valve, likely due to mitral valve vegetations, protruding during systole into the left ventricular outflow tract. The presence of mitral valve vegetation was confirmed at operation.
