Pheochromocytoma Presenting with Multiple Cardiovascular Manifestations

A 56-year-old man presented with sudden onset of congestive heart failure (New York Heart Association class III to IV) after mild stress and developed various cardiovascular manifestations. At first visit, cardiac enzyme elevation, regional left ventricular (LV) wall motion abnormality and pulmonary edema were evident. However, coronary angiography was normal. LV function was totally recovered at discharge, suspicious of fulminant myocarditis. During the hospital stay, acute non-obstructive stroke without neurologic sequelae occurred. After 3 years, he re-admitted because ventricular tachycardia and severe LV systolic dysfunction (ejection fraction, 15%) were developed. After 3 days of applying percutaneous cardiopulmonary bypass system, the patient was completely recovered. Suspicious of pheochromocytoma, we checked 24-hour urine catecholamines and metanephrines and abdomen computed tomography, which revealed pheochromocytoma. The patient underwent laparoscopic adrenalectomy.
