Abstract

We report a case of a true cleft in the anterior leaflet of the mitral valve. The cleft, however, is directed toward the ventricular septum, and the left ventricular papillary muscles have the same arrangement as seen in the setting of a common atrioventricular orifice. The atrioventricular septum is intact. This appearance reflects the presence, in this patient, of right ventricular origin of a solitary arterial trunk, so that there was no outflow tract within the left ventricle to interpose between the mitral valve and the septum.
