6 | CONCLUSIONS
PFA with the ablation strategy including PVI, LAPW isolation, CTI block, and MI block is feasible, safe, and associated with a high rate of freedom from atrial tachyarrhythmia recurrence at 1 year in patients with PeAF. Nevertheless, the PFA systems still need to optimize catheter design and ablation parameters to enhance acute success rates, reduce reconnections, improve transmural lesion durability, and minimize risks.
