Utility of routine transesophageal echocardiography in patients with stroke or transient ischemic attack

Abstract In several series of patients with presumed stroke, transesophageal echocardiography (TEE) has seemed advantageous over transthoracic echocardiography (TTE) in that it improves detection of cardiac sources and can lead to changes in the methods of treatment. We hypothesized that the real-world application of TEE in our institution produced results at variance from those previously reported. Our study of 219 patients, referred for TEE for an indication of stroke or transient ischemic attack, found few relevant findings that would have indicated a new diagnosis or required a change in treatment. These results suggest that for most patients in whom TEE is ordered, either a TTE or no cardiac testing would suffice.
