We describe the occurrence of acute myocardial infarction during transesoph
ageal echocardiography (TEE) in a patient with atrial fibrillation and unde
restimated angina. Such a case has not been previously reported in the lite

ding us to suggest systematic sedation in patients with angina in whom TEE
is envisaged.
