“…Since the establishment of PVI due to advances in catheter technologies and techniques, numerous studies have demonstrated LA reverse remodeling due to restoration and maintenance of sinus rhythm after PVI. 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 27 , 28 , 29 , 30 , 31 Regarding LA structural reverse remodeling, meta‐analyses revealed that LA diameter and LA volume were significantly decreased by AF ablation. 18 , 19 On the other hand, although the LA function was also improved by successful RFCA, several studies have reported persistent LA functional abnormalities after effective ablation.…”
