Aortic Valve Area, Stroke Volume, Left Ventricular Hypertrophy, Remodeling, and Fibrosis in Aortic Stenosis Assessed by Cardiac Magnetic Resonance Imaging

Abstract

CMR confirmed overall accuracy of echocardiographic classification of AS but demonstrated that LG/LF and LG/NF AS have larger AVA, less LV hypertrophy, and similar focal fibrosis compared with HG/LF AS. This challenges the view that LG/LF AS is a more advanced state of AS.
