Objectives This study aimed to evaluate the progression of electrophysiological phenomena
in a cohort of patients with paroxysmal atrial fibrillation (PAF) and persistent atrial fibrillation …

Atrial fibrillation (AF) is a major cause of heart failure and stroke. The early maintenance of
sinus rhythm has been shown to reduce major cardiovascular endpoints, yet is difficult to …

Up to 65% of patients with heart failure with preserved ejection fraction (HFpEF) develop AF
during the course of the disease. This occurrence is associated with adverse outcomes …

Abstract Background Persistent atrial fibrillation (PerAF) is often associated with right atrial
(RA) enlargement. We investigated the efficacy of RA intervention in patients with PerAF and …

Background and purpose Tricuspid regurgitation (TR) is a common but overlooked valvular
disease, and its association with the etiologic subtypes of ischemic stroke is unclear. We …

Background Little is known regarding the characterization of electrical substrate in both atria
in patients with atrial fibrillation (AF). Methods Eight consecutive patients undergoing AF …

Objective This study aimed to assess the effect of the lesion sets for surgical ablation of atrial
fibrillation on long-term outcomes and identify the optimal lesion set. Methods Between 2005 …

Background: The role of dominant frequency (DF) in tracking the efficiency of a stepwise
catheter ablation (step-CA) in persistent atrial fibrillation (peAF) remains poorly studied. We …

Objective This study sought to study the feasibility, efficacy, and safety of using multiscale
entropy (MSE) analysis to guide catheter ablation for persistent atrial fibrillation (PsAF) and …

The idea of using advanced electrogram signal analysis to guide ablation of persistent atrial
fibrillation (AF) has been explored repeatedly. The seminal report from Nademanee et al.(1) …
