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.
