Dilated cardiomyopathy (DCM) is a highly prevalent disease which has multiple clinical manifestations and pathological features. With the characteristics of multi-sequence and multi-parameter, cardiac magnetic resonance imaging (MRI) can accurately assess the morphology, function and tissue characterization of heart, and provide comprehensive information for diagnosis of DCM. This review focuses on the sequences and clinical applications of MRI evaluation in DCM in order to provide additional information for clinical diagnosis, treatment and prognosis.
Catecholamine-induced cardiomyopathy in pheochromocytoma/paraganglioma (PPGL) is a potential fatal cardiovascular complication caused by excessive secretion of catecholamines by PPGL, leading to structural changes and functional abnormalities in the heart. According to the morphology and function of the heart, it is clinically divided into three types: dilated cardiomyopathy, Takotsubo cardiomyopathy, and hypertrophic cardiomyopathy. The treatment of catecholamine-induced cardiomyopathy in PPGL requires attention to drug selection, application of life support equipment, and perioperative management. Most patients with cardiac dysfunction can effectively improve after tumor resection. This article mainly reviews the diagnosis and treatment of catecholamine-induced cardiomyopathy in PPGL.
