Takotsubo syndrome during surgery for pheochromocytoma: an unexpected complication.

Takotsubo syndrome is a rare cause of systolic dysfunction and can be found as a clinical manifestation of pheochromocytoma. We present a case of rapid onset of systolic dysfunction with cardiogenic shock, which developed after the surgical excision of an adrenal gland tumor in a 60-year-old male. Coronary angiography excluded coronary artery disease. The echocardiography and ventriculography images suggested Takotsubo cardiomyopathy pattern. Following 2 weeks of inotropic and vasopressor therapy, the left ventricular function gradually improved, until complete resolution.
