Figure 1 (A) Parasternal short-axis echocardiographic view in a patient with cleft mitral valve and subaortic stenosis. Note the normal position of the papillary muscles with a normally developed mural leaflet (arrows). (B) Spectral Doppler velocity through a severe subaortic stenosis due to the cleft. (C) Parasternal long-axis echocardiographic view showing the narrowest subaortic area with aliasing of the color velocities. AL = anterolateral papillary muscle; AO = aorta; LA = left atrium; LV = left ventricle; PM = posteromedial papillary muscle.

Figure 2 (A) Subcostal echocardiographic view in a patient with cleft mitral valve and no chordal attachment to the ventricular septum. (B) Intraoperative view of the cleft (*). Note the thickness of the cleft edges with retraction of both parts of the anterior leaflet (arrows). LV = left ventricle.
