✦ Synopsis
Atrial septal aneurysm (ASA) is a rare, localized deformity of the atrial septum that is usually identified as a n incidental finding by twodimensional echocardiography .' Because the lesion is located far from the transducer on the chest wall, it is apparent that transesophageal echocardiography (TEE) is superior to transthoracic echocardiography (TTE) in visualizing the morphology of ASA.' However, misdiagnosis may at times occur because of the polymorphous presentation of ASA.3 In this report, we present two patients with large ASAs appearing as right atrial masses by TEE.
