Background—The pulmonary veins (PVs) and surrounding ostial areas frequently house
focal triggers or reentrant circuits critical to the genesis of atrial fibrillation (AF). We developed …

Background— There are no data to evaluate the relationship between autonomic nerve
function modification and recurrent atrial fibrillation (AF) after circumferential pulmonary vein …

Objectives : We compared ablation strategy with antiarrhythmic drug therapy (ADT) in
patients with paroxysmal atrial fibrillation (PAF). Background : Atrial fibrillation (AF) ablation …

Background We conducted a randomized, controlled trial of circumferential pulmonary-vein
ablation for the treatment of chronic atrial fibrillation. Methods A total of 146 patients with a …

Background Circumferential radiofrequency ablation around pulmonary vein (PV) ostia has
recently been described as a new anatomic approach for atrial fibrillation (AF). Methods and …

Objectives : This study was designed to investigate the potential of circumferential pulmonary
vein (PV) ablation for atrial fibrillation (AF) to maintain sinus rhythm (SR) over time, thus …

Background— Radiofrequency ablation for atrial fibrillation is becoming widely practiced.
Methods and Results— Two patients undergoing circumferential pulmonary vein ablation for …

Background—We treated paroxysmal recurrent atrial fibrillation (AF) with radiofrequency (RF)
catheter ablation by creating long linear lesions in the atria. To achieve line continuity, a …

Background— Circumferential pulmonary vein ablation (CPVA) is effective in curing atrial
fibrillation (AF), but new-onset left atrial tachycardia (AT) is a potential complication. We …

Objectives : We assessed feasibility of magnetic catheter guidance in patients with atrial
fibrillation (AF) undergoing circumferential pulmonary vein ablation (CPVA). Background : No …
