Identification of subclinical cardiac amyloidosis in aortic stenosis patients undergoing transaortic valve replacement using radiomic analysis of computed tomography myocardial texture
Journal of cardiovascular computed tomography(2023)
摘要
Clinical presentation associated to cardiac amyloidosis (CA) shows an increased biventricular wall thickness, myocardial stiffening and ventricles restrictive physiology caused by amyloid myocardial deposition. 1 Bonelli A.
