The aim of this study was to evaluate the rate of bleeding, thromboembolic complications, and the rate of stent thrombosis or restenosis in patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI). In this retrospective analysis, we included patients with AF who underwent PCI with stent implantation from 2003 to 2006.(More)
BACKGROUND Nonrandomized studies have reported focal impulse and rotor modulation (FIRM)-guided ablation to be superior to pulmonary vein antrum isolation (PVAI) for persistent atrial fibrillation and long-standing persistent atrial fibrillation. OBJECTIVES This study sought to compare efficacy of FIRM ablation with or without PVAI versus PVAI plus non-PV(More)
UNLABELLED Paradoxical atrial undersensing. BACKGROUND Paradoxical atrial undersensing at high atrial sensing levels was described as false atrial noise reversion of dual-chamber pacemakers during atrial fibrillation in a sheep model. It is unknown whether this phenomenon occurs in humans. METHODS In total, 71 patients with implanted dual-chamber(More)
BACKGROUND Endoscopically detected esophageal lesions (EDELs) have been identified in apparently asymptomatic patients after catheter ablation of atrial fibrillation (AF). The use of esophageal probes to monitor luminal esophageal temperature (LET) during catheter ablation to protect esophageal damage is currently controversial. OBJECTIVE The purpose of(More)
Aims Oesophageal probes to monitor luminal oesophageal temperature (LET) during atrial fibrillation (AF) catheter ablation have been proposed, but their effects remain unclear. Aim of this study is to evaluate the effects of an oesophageal temperature probe with insulated thermocouples. Methods and results Patients with symptomatic, drug-refractory(More)
Aims Aim of this study was to evaluate the impact of a recently introduced contact force ablation catheter with modified irrigation technology compared with a conventionally irrigated ablation catheter on the incidence of endoscopically detected oesophageal lesions (EDEL). Methods and results Patients with symptomatic, drug-refractory paroxysmal or(More)
BACKGROUND Single-shot ablation devices for pulmonary vein isolation (PVI) in patients with symptomatic atrial fibrillation (AF) have been increasingly used in clinical practice. OBJECTIVE A novel mapping-system integrated irrigated multipolar circular ablation catheter (nMARQ) has been introduced for PVI but data on larger patient cohorts on acute safety(More)
BACKGROUND Up to 40% of patients demonstrate endoscopically detected asymptomatic esophageal lesions (EDEL) after atrial fibrillation ablation. METHODS AND RESULTS Patients undergoing first atrial fibrillation ablation and postinterventional esophageal endoscopy were included in the study. Occurrence of esophageal perforating complications during(More)
INTRODUCTION Focal impulses (FI) and rotors are sources associated with the initiation and maintenance of atrial fibrillation (AF). Their ablation results in a lower recurrence rate. The aim of this study was to characterize for the first time the spatial relationship between such sources and atrial low voltage zones (LVZ) representing fibrosis. METHODS(More)
Silent cerebral events (SCE) have been identified on cerebral diffusion-weighted cerebral magnetic resonance imaging (DE-MRI) after catheter ablation (CA) of atrial fibrillation (AF). The purpose of this study was to investigate the impact of atrial remodeling on the incidence of SCE after AF CA. Forty patients (67.8 ± 10 years, 47.5 % women) with(More)
