May support TEE for etiology workup in select undetermined strokes; leaves open whether it improves outcomes.
Does transesophageal echocardiography (TEE) improve the determination of stroke etiology and influence therapeutic strategies in patients with acute brain ischemia?
TEE significantly impacts secondary prevention strategies by identifying indications for oral anticoagulation in approximately one-third of stroke patients with initially undetermined etiology.
Harloff et al. (2006) studied this question.
