Background— Together with pulmonary veins, many extrapulmonary vein areas may be the
source of initiation and maintenance of atrial fibrillation. The left atrial appendage (LAA) is …

Background— Catheter ablation of atrial fibrillation is associated with the potential risk of
periprocedural stroke, which can range between 1% and 5%. We developed a prospective …

BACKGROUND/OBJECTIVE: The purpose of this prospective multicenter study was to compare
results of catheter ablation in patients with paroxysmal atrial fibrillation (PAF) and those …

Objectives : We present the initial clinical human experience with the use of a robotic remote
navigation system (Hansen Medical, Mountain View, California), to perform left and right …

Background— Obstructive sleep apnea (OSA) may be associated with pulmonary vein antrum
isolation (PVAI) failure. The aim of the present study was to investigate if treatment with …

Background— Multiple morphologies, hemodynamic instability, or noninducibility may limit
ventricular tachycardia (VT) ablation in patients with arrhythmogenic right ventricular …

Introduction: Electrical storm (ES) is characterized by either refractory ventricular tachycardia
(VT) or ventricular fibrillation (VF). However, little is known about the prevalence, predictors, …

Background— Left atrioesophageal fistula is a devastating complication of atrial fibrillation
ablation. There is no standard approach for avoiding this complication, which is caused by …

Background— Left atrioesophageal fistula is a rare but devastating complication that may
occur after catheter ablation of atrial fibrillation. We used capsule endoscopy to assess …

Background: Ablation of atrial fibrillation is generally considered safe and effective. However,
atrial–esophageal fistulas have recently been reported as a rare but fatal complication. …
