Prognostic Impact of Myocardial Extracellular Volume Fraction Assessment Using Dual‐Energy Computed Tomography in Patients Treated With Aortic Valve Replacement for Severe Aortic Stenosis

Background Myocardial extracellular volume fraction (ECV), measured by cardiac magnetic resonance imaging, is a useful prognostic marker for patients who have undergone aortic valve replacement (AV...
