Transthoracic echocardiographic images of the left atrial mass. A 2D-echocardiography: Four chamber view demonstrates a large, echogenic mass attached to the lateral left atrial wall, prolapsing across the mitral valve causing left ventricular inflow obstruction. LA = left atrium, LV = left ventricle, MV = mitral valve, RUPV = right upper pulmonary vein, LUPV = left upper pulmonary vein. B 2D-echocardiography: Parasternal long axis view demonstrating obstruction of LV inflow with the mass prolapsing from the left atrium, across the mitral valve and into the left ventricle. C 3D-echocardiography demonstrating a large, well-circumscribed, echogenic mass (white arrow) filling the left atrium (LA). The aortic valve (AV) is oriented at the 12 o’clock position
