[Pheochromocytoma and catecholamine cardiomyopathy].

We describe a 40 years old patient deceased of pheochromocytoma-caused heart failure, with no previous specific symptomatology. At autopsy the heart was characterised by thin cardiac walls and cavity dilatation. Histologic pattern showed extensive myocardial fibrosis and some acute myocytolytic areas. This pattern is equal to that of prolonged and decompensated stress cardiomyopathy. These pathologic pictures are both caused by catecholamines cardiotoxicity.
