title: [Clinical evaluation of "Takotsubo" cardiomyopathy with 123I-MIBG myocardial scintigraphy: a case report].
abstract: We report a case of "Takotsubo" cardiomyopathy that was considered to be caused by hypercatecholaminemia due to mental stress. Myocardial scintigraphy using 123I-MIBG revealed severe damage to the myocardial sympathetic nerve terminals at the site of reduced left ventricular wall motion on left ventriculography. In this case, cardiac nuclear imaging with 123I-MIBG appeared to be useful for understanding the pathophysiology when combined with ECG and left ventriculography.
