Post-operative atrial fibrillation (POAF) is one of the most frequent complications of cardiac
surgery and an important predictor of patient morbidity as well as of prolonged …

Atrial fibrillation (AF) is commonly associated with overweight and obesity. Both conditions
have been identified as major global epidemics associated with increased mortality and …

Background—The electropathological substrate of persistent atrial fibrillation (AF) in humans
is largely unknown. The aim of this study was to compare the spatiotemporal characteristics …

Background Pulmonary vein isolation (PVI) in conjunction with isolation of the posterior left
atrial wall (PVI+ PWI) is associated with improved clinical outcomes in certain patients with …

Objectives The aim of this multicenter, randomized, single-blind study was to prospectively
evaluate the short-and long-term outcomes of pulmonary vein isolation (PVI) versus PVI with …

Ranolazine is a Food and Drug Administration–approved antianginal agent. Experimental
and clinical studies have shown that ranolazine has antiarrhythmic effects in both ventricles …

Rationale: Electrogram-based catheter ablation, targeting complex fractionated atrial
electrograms (CFAEs), is empirically known to be effective in halting persistent/permanent …

Epicardial Adipose Tissue in Atrial Fibrillation. Introduction: As epicardial adipose tissue
(EAT) is a metabolically active visceral fat, potential interaction between EAT and …

Diabetes mellitus (DM) is an independent risk of atrial fibrillation. However, its
arrhythmogenic substrates remain unclear. This study sought to examine the precise …

Background—Atrial stretch causes remodeling that predisposes to atrial fibrillation. We
tested the hypothesis that peaks in left atrial (LA) wall stress are associated with focal …
