Abstract:
Objective: To compare the efifcacy and safety of circumferential pulmonary vein antecourt isolation (CPVAI) ablation and stepwise linear (SL) ablation in treating the patients with atrial ifbrillation (AF) Methods: A total of 136 AF patients with catheter ablation under EnSite 3000 guidance in our hospital were retrospectively summarized. The patients included 93 paroxysmal AF and 43 persistent AF and divided into 4 groups. Paroxysmal AF with CPVAI ablation,n=45, Paroxysmal AF with SL ablation,n=48 and persistent AF with CPVAI ablation, n=18, persistent AF with SL ablation,n=25. The differences of left atrium diameter, ablation time, X-ray exposure time, the success rate and complication were compared among different groups. Results: For 12 months follow-up study, the success rate and complication were similar between 2 ablation methods for treating both Paroxysmal AF and persistent AF patients. For Paroxysmal AF patients, both ablation methods could effectively reduce left atrium diameter,P<0.01. The SL ablation had less procedural time than CPVAI ablation,P<0.01, while the X-ray exposure time was similar between 2 ablation methods. Conclusion: Both CPVAI and SL ablation methods were effective and safe for treating AF patients.
