Association of Cardiac CT‐Derived Epicardial Adipose Tissue With Atrial Fibrillation in Patients Without Left Atrial Fibrosis as Defined by Endocardial Voltage Mapping

EAT volume is greater in AF patients without evidence of LA fibrosis compared to matched controls without AF. These findings support an association of EAT with AF pathogenesis even in the absence of LA fibrosis.
