Feasibility of Auto-Quantified Epicardial Adipose Tissue in Predicting Atrial Fibrillation Recurrence After Catheter Ablation

Abstract

in ablation therapy, many patients continue to experience complications and relapse of AF. Atrial structural remodeling is one of the main causes of AF occurrence and deterioration after CA. Previous studies have demonstrated distinct left atrial (LA) remodeling with increased LA volume, which is associated with a higher risk of AF recurrence after CA. 4 In addition, the other well-known marker, epicardial adipose tissue (EAT), which is an active A trial fibrillation (AF) is the most common sustained arrhythmia, significantly increasing the risk of adverse events such as ischemic stroke, coronary artery disease, heart failure, and mortality. 1 Catheter ablation (CA) is a well-established treatment for symptomatic anti-arrhythmic drug-refractory AF and can significantly improve the quality of life of patients with AF. 2,3 Despite ongoing medical and technological advances
