Key result
Transesophageal echocardiography identified an atrial septal aneurysm with superimposed thrombus as a rare cause of systemic emboli and multiple cerebral infarcts.
Transesophageal echocardiography is crucial for diagnosing atrial septal aneurysm with superimposed thrombus as a rare cause of systemic emboli.
May support TEE in unexplained emboli; leaves open prospective studies on atrial septal aneurysm thrombus.
The authors describe the case of a patient referred for evaluation of multiinfarct dementia. Conventional echocardiography revealed an aneurysm of the interatrial septum. A transesophageal echocardiogram demonstrated superimposed thrombus. This rare cause of systemic emboli can be diagnosed only by transesophageal echocardiography and is of major interest to avoid recurrence of ischemic strokes.
