Periatrial Epicardial Adipose Tissue as a Predictor of Substrate Distribution and Atrial Arrhythmia Recurrence in Patients with Early Atrial Remodeling.
BACKGROUND Epicardial adipose tissue (EAT) is hypothesized to induce atrial remodeling. However, no prior studies have evaluated the spatial relationship between EAT and early atrial substrate. Given atrial fibrosis may progress from epi- to endocardium, unipolar voltage may be a more sensitive marker of early remodeli...
