NCT06499818

Brief Summary

The primary objective of this investigation is to compare the efficacy of Three different AF ablation strategies in patients with Persistent atrial fibrillation: CPVI plus Low-Voltage Areas ablation during sinus rhythm Versus. CPVI Plus Low-Voltage Areas Ablation During AF and CPVI alone.
