To the Editors: The recent reports by Tunick and colleagues (1, 2) showing how transesophageal echocardiography (TEE) can implicate aortic arch atheromata in the causation of systemic emboli without previously known sources were interesting. The discovery of the cause of a previously mysterious event is intellectually satisfying.
However, I am concerned about how TEE will be used—if it is not already on its way to becoming a "standard of care." The evaluation of embolic strokes now includes computed tomography (or magnetic resonance imaging) of the brain, cardiac echocardiography, and carotid noninvasive studies and may grow to include TEE to search
