Abstract： Objective To investigate the efficacy of circumferential pulmonary vein isolation guided by Ensite3000 3D mapping system in patients with atrial arrythmia. Methods Consecutive patients with atrial arrhythmia underwent circumferential pulmonary vein isolation guided by Ensite3000 3D mapping system. Disappearance of pulmonary vein potential was considered as the ablation endpoint.Success was defined as without atrial tachyarrhythmia after 3 months,as well as asymptomatic atrial tachyarrhythmia. Results Clinical success achieved 71.8% and the effective rate was 12.6% in 64 patients. Severe complications included 2 cases of pericardial tamponade and 2 cases of mild pericardial effusion,1 case of femoral embolism and 1 case of arteriovenous fistula. There was no death case. Conclusion Circumferential pulmonary vein isolation guided by Ensite3000 3D mapping system is an effective therapy and safe for patients with atrial arrhythmia.
