Multicenter Study
Safety and efficacy of pulmonary vein isolation using a circular, open-irrigated mapping and ablation catheter: A multicenter registry.
Pulmonary vein (PV) isolation is the cornerstone of catheter ablation in patients with atrial fibrillation (AF). "Single-shot" ablation devices have been recently engineered. ⋯ In this multicenter registry, irrigated multielectrode RF ablation proved feasible, achieving a high rate of isolated PVs. Procedural and fluoroscopy times and success rates were comparable with other techniques, with a low complication rate.
