However, in patients with persistent AF, PVI alone is often insufficient, and no adjunctive strategy with proven efficacy beyond PVI has been established. Recently, increasing attention has been directed toward local atrial conduction velocity (CV). Slow conduction velocity areas (SCVAs) have been regarded as potential arrhythmogenic substrates, and ablation strategies targeting SCVAs are under investigation. This study evaluated the efficacy of SCVA-guided ablation in patients with persistent AF.</p><p><strong>Methods: </strong>We enrolled 175 patients with persistent AF who underwent initial radiofrequency catheter ablation (RFCA).
