May support AI-guided high-power ablation in AF procedures; hypothesis-generating pending randomized confirmation of durability.
Dhillon et al. (2018) conducted a cohort in Paroxysmal atrial fibrillation (n=100). High power ablation guided by ablation index vs. Conventional ablation guided by force-time integral was evaluated on Acute pulmonary vein reconnection (p=0.015). High-powered ablation guided by ablation index reduced acute pulmonary vein reconnection compared with conventional ablation (14% vs 24%; P=0.015) and shortened procedure times.
