  Fig. 1 2D (A) and 3D (B and C) transesophageal echocardiography appearance of lipomatous hypertrophy of the interatrial septum (IAS, asterisks) can be summarized as: 1) IAS thickening > 2 cm, 2) a projection of the mass only into the right atrium, 3) a homogenous appearance of the mass, 4) sparing the membrane of the fossa ovalis (arrows) that, in case of affecting proximal and distal part of IAS, might result in characteristic bilobal (dumbbell shape) IAS appearance. LA: left atrium, RA: right atrium, SVC: superior vena cava, IVC: inferior vena cava.
