Figure 1 Intraoperative transesophageal echocardiography images demonstrating systolic anterior motion of the anterior mitral valve leaflet (upper right panel) and an interleaflet gap (lower left panel) through which a jet of mitral regurgitation (lower right panel) is centrally directed into the left atrium. The central jet is due to the combination of LVOT obstruction and posterior mitral valve leaflet prolapse. Ao = aorta; LA = left atrium; LV = left ventricle.
