Fig. 13From: Complex and multilevel left ventricular outflow tract obstruction: What can 3D echocardiography add?Right upper panel, 2D TOE (ME aortic long-axis view) shows small rims of the subaortic membrane seen immediately adherent to the aortic cusps. Left upper panel, 2D TOE (ME aortic short-axis view) shows the trileaflet aortic valve. Right lower panel, 2D TOE (TG aortic long-axis view) shows a small tunnel of the LVOT. Left lower panel, 2D TOE (TG short axis of the LV) shows hypertrophy of the left ventricle and papillary musclesBack to article page
