Assessment of Diffuse Ventricular Fibrosis in Atrial Fibrillation Using Cardiac CT-Derived Myocardial Extracellular Volume Fraction

In patients with atrial fibrillation (AF), diffuse left ventricular (LV) fibrosis may occur as a result of AF-induced or -mediated cardiomyopathy (AF-CM). It is believed that AF-CM is triggered in part due to tachycardia, irregular rhythm, dyssynchrony, lack of atrial contraction, and functional
