Overview
Brief Summary
Acute efficacy of point-by-point radiofrequency ablation for pulmonary vein isolation in patients with atrial fibrillation are comparable independantly of the ablation strategy (continous versus discontinuous ablation) under the same condition of power delivery.
Detailed Description
The number of pulmonary vein isolation (PVI) therapy for atrial fibrillation (AF) is increasing. Durable PVI is cornerstone for long-term freedom of AF. In one previous study continuous ablation was suggested to be more efficient in durable PVI. However, this hypothesis has not been proven in randomized fashion. The current study is to confirm whether continuous versus discontinuous design of encircling lesions are comparable under the same conditions of power delivery. The study design is a two-centre prospective randomized trial to compare the acute efficacy by using the above described approaches.
