[Catecholamine-induced myocarditis in pheochromocytoma].
Pheochromocytoma is a rare tumor, usually benign, potentially lethal in case of crisis with acute release of catecholamines. The heart is a target and the clinical presentation can mimic various cardiac conditions, thus rendering diagnosis elusive. Cardiac magnetic resonance is a valuable non-invasive diagnostic tool for the evaluation of cardiomyopathies; it allows the identification of catech...
متن کاملPheochromocytoma-Induced Acute Myocarditis
Pheochromocytoma is a neuroendocrine tumor, characterized by an excess of catecholamine production, which results in paroxysmal or sustained hypertension, even hypertensive crisis. The classic triad of pheochromocytoma is paroxysmal headache, sweating and palpitation. Myocarditis is a rare manifestation of pheochromocytoma. We report 2 middle-aged women with a long history of hypertension and h...
متن کاملAdrenergic Myocarditis in Pheochromocytoma
The clinical presentation of pheochromocytoma is variable and many biochemical and imaging methods have been suggested to improve the diagnostic accuracy of what has been termed "the great masquerader". This case-report is of a middle-aged woman with a non-specific clinical presentation suggesting acute coronary syndrome or subacute myocarditis. Cardiovascular magnetic resonance (CMR) at presen...
متن کاملRecurrent Catecholamine-Induced Cardiomyopathy in a Patient With a Pheochromocytoma
Pheochromocytomas presents with variable clinical manifestations. Cardiomyopathy caused by a pheochromocytoma is well known. We report the case of a 62-year-old woman with recurrent left ventricular dysfunction, who was subsequently found to have a pheochromocytoma. The patient had two different patterns of cardiomyopathy. Patients with a cardiomyopathy, of non-specific origin, should have a ph...
متن کاملPheochromocytoma Is Characterized by Catecholamine-Mediated Myocarditis, Focal and Diffuse Myocardial Fibrosis, and Myocardial Dysfunction.
BACKGROUND Pheochromocytoma is associated with catecholamine-induced cardiac toxicity, but the extent and nature of cardiac involvement in clinical cohorts is not well-characterized. OBJECTIVES This study characterized the cardiac phenotype in patients with pheochromocytoma using cardiac magnetic resonance (CMR). METHODS A total of 125 subjects were studied, including patients with newly di...
