Main findings
The study presented here demonstrated that significant impact of the PLS ablation in patients with persistent AF. With the primary goal of our study to determine whether the PLS ablation could terminate AF, we concluded that the ratio of AF termination during the PLS ablation was almost 50%. The secondary goal was to assess whether the rhythm outcome after the PLS ablation could be improved as compared to that after conventional ablation. During a median 9 months follow-up, the AF recurrence was significantly less in the PLS ablation group as compared to the conventional ablation group. Furthermore, we concluded by means of multivariate analysis that the PLS ablation was only associated with a freedom from the AF recurrence.
