Key result
Ablation index-guided 50 W radiofrequency ablation significantly reduced total procedure time compared to 35-40 W ablation (120 vs. 143 mins, p=0.004) with comparable 12-month outcomes.
Why the study?
Ablation index-guided ablation for posterior wall isolation using high-power, short-duration remained untested.

AI-guided 50 W radiofrequency ablation reduces total procedure time and individual lesion ablation time without compromising acute success or 12-month outcomes compared to conventional 35-40 W ablation.
Ding et al. (2022) conducted a cohort in atrial fibrillation (n=40). Ablation index-guided 50 W radiofrequency ablation vs. 35-40 W conventional ablation was evaluated on Total procedure time (minutes) (p=0.004). Ablation index-guided 50 W radiofrequency ablation significantly reduced total procedure time compared to 35-40 W ablation (120 vs. 143 mins, p=0.004) with comparable 12-month outcomes.
