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 کاملImaging of cardiac adrenergic innervation.
Cardiac myocytes and the coronary circulation are innervated by both sympathetic and parasympathetic fibres which constitute the autonomic nervous system. 2 The autonomic outflow is controlled by regulatory centres in the midbrain, hypothalamus, pons, and medulla which integrate inputs from other brain areas as well as afferent stimuli from the periphery. The efferent signals follow descending ...
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 کاملCardiac magnetic resonance strain imaging in systemic light chain amyloidosis
Background Systemic light chain amyloidosis (AL) is associated with a high cardiovascular morbidity and mortality. Cardiovascular involvement and determination of prognosis is underestimated by standard imaging parameters. Recently, cardiac deformation analysis of global circumferential and longitudinal strain has been shown to have great clinical impact on the assessment of prognosis and survi...
