The disorder is frequently associated with episodes of mental or physical stress, implicating an abnormal cardiac response to increased catecholamines. Although death has been reported during the index event, the long\u2010term prognosis is good with full recovery of left ventricular function. We present a case of Takotsubo cardiomyopathy mimicking anterior ST segment elevation myocardial infarction precipitated by dobutamine stress testing. Reinfusion of dobutamine in the catheterization laboratory reproduced symptoms with angiography and intravascular ultrasound supporting the theory of abnormal microvascular circulation as the etiology of Takotsubo cardiomyopathy. Acute and delayed magnetic resonance imaging demonstrated no infarction with complete recovery of ventricular function. \u00a9 2005 Wiley\u2010Liss,
