[Pheochromocytoma with reversal of tako-tsubo-like transient left ventricular dysfunction: a case report]

Abstract

A 59-year-old male was admitted to the emergency department because of sustained chest oppression. Electrocardiography revealed J type ST depression and peaked T wave in leads II, III, aVF, and V4-V6. No stenosis was found in the coronary arteries by urgent coronary angiography. Left ventricular abnormal wall movement with akinesis in the base and hyperkinesis in the apical area was observed and improved on the 12th day. Myocardial scintigraphy with iodine-123-metaiodobenzylguanidine showed completely defective images and decreased accumulation in the base with combined thallium-201 and iodine-123-beta-methyl-p-iodophenyl-pentadecanoic acid. Myocardial biopsy on the 12th day disclosed contraction band necrosis. The diagnosis was catecholamine-induced cardiomyopathy caused by pheochromocytoma.
