Atrial fibrillation (AF) is an arrhythmia that can occur as the result of numerous different
pathophysiological processes in the atria. Some aspects of the morphological and …

Aims This multicentre, randomized trial compared three strategies of AF ablation: ablation of
complex fractionated electrograms (CFE) alone, pulmonary vein isolation (PVI) alone, and …

Ablation strategies targeting areas of complex fractionated atrial electrograms are not
successful for treatment of atrial fibrillation. Fractionation of atrial electrograms may have …

Background The clinical significance of left atrial pressure (LAP) has not yet been clearly
elucidated in patients with atrial fibrillation (AF). Objective To explore the effects of elevated …

Background—Catheter ablation of atrial fibrillation (AF) became an effective therapy for
patients with drug-refractory AF, and the indications have broadened to include …

Previous studies have reported that increased high-sensitive C-reactive protein (hs-CRP)
levels are associated with an inflammatory state. This study investigated the association …

Background: The efficacy of ablation of complex fractionated atrial electrograms (CFEs) in
the single ablation procedure for nonparoxysmal atrial fibrillation (AF) patients is not well …

Dominant Frequency Mapping and Ablation. Background: Sites of high DF are potential
targets for AF ablation, but it is unknown if addition of DF ablation can improve procedural …

Objectives Epicardial fat was closely related to atrial fibrillation (AF). Transthoracic
echocardiography (TTE) has been proposed to be a convenient imaging tool in assessing …

BACKGROUND: It has been proposed that sequential mapping of dominant frequency (DF)
and complex fractionated atrial electrograms (CFAE) can identify target sites for ablation of …
