Imaging cardiac innervation in amyloidosis.
Cardiac amyloidosis is a form of restrictive cardiomyopathy resulting in heart failure and potential risk on arrhythmia, due to amyloid infiltration of the nerve conduction system and the myocardial tissue. The prognosis in this progressive disease is poor, probably due the development of cardiac arrhythmias. Early detection of cardiac sympathetic innervation disturbances has become of major cl...
متن کاملCardiac MR imaging genotoxicity?
Magnetic resonance (MR) imaging, including cardiac MR (CMR), is an important, widely used diagnostic tool, and is generally considered a safer alternative to X-ray and radioisotope imaging where there is a clear relationship between exposure to ionizing radiation and increased cancer risk. MR imaging exposes the patient to a mixture of static magnetic fields, time-varying gradient fields, and p...
متن کاملMagnetic resonance imaging in cardiac amyloidosis.
The amyloidoses are a group of uncommon systemic diseases characterized by the extracellular deposition of pathologic insoluble amyloid protein in organs and tissues. The are 4 main types of amyloidosis: primary (AL, the most prevalent type), familial, secondary, and senile. Each of them has its own physiopathology, distinctive features, and variable cardiac involvement. The symptoms of cardiac...
متن کاملTypical cardiac magnetic resonance imaging findings of cardiac amyloidosis.
We report the case of a 62-year-old man who presented with shortness of breath, lower extremity edema and clinical signs of congestive heart failure. Transthoracic echocardiography demonstrated concentric left ventricular hypertrophy with severe diastolic dysfunction and biatrial enlargement. After aggressive diuresis and clinical improvement, a cardiac magnetic resonance imaging (CMR) examinat...
متن کاملPerforming cardiac MR imaging: an overview.
Because of the enormous economic and social impact of cardiovascular disease in the United States, there is a need for improved noninvasive diagnosis. Cardiac MR imaging is a versatile, comprehensive technique for assessing cardiac morphology and function. With an understanding of cardiac anatomy and physiology as well as MR physical principles, cardiac MR imaging can be performed and play an i...
