Transesophageal echocardiographic assessment of a floating thrombus located in the ascending aorta.

Transesophageal echocardiography (TEE) has become a unique imaging technique that provides improved visualization of aorta because of its proximity to the esophagus. It is a reliable method for the diagnosis of thoracic aorta diseases and detection of protruding atheromas or thrombi as sources of systemic emboli. We report a case in which TEE revealed a floating aortic thrombus located in the ascending aorta in a patient with chronic renal failure.
