((a) and (b)) Transthoracic echocardiography showing massive left atrial invasion by a large multilobed mass, with protrusion through the mitral valve into the left ventricle during diastole (arrow). ((c) and (d)) Transesophageal echocardiography confirming left atrial invasion by a large mass entering the left ventricle in diastole and showing regions of cystic colliquation within the mass (arrow). AO, aorta; LA, left atrium; LAA, left atrial appendage; LV, left ventricle; RA, right atrium; RV, right ventricle.
