To search the source of these emboli, aortic arch mass should be considered. To our knowledge, transesophageal echocardiography (TEE) can be a useful modality to demonstrate the nature and exact location of the mass. This report is illustrative of a large mobile aortic arch mass, histologically thrombus, found by TEE in a 48- year–old woman with embolic symptoms.        https://rhythm.tums.ac.ir/index.php/jthc/article/view/53 https://rhythm.tums.ac.ir/index.php/jthc/article/download/53/51
