Pulmonary vein isolation guided by moderate ablation index targets combined with strict procedural endpoints for patients with paroxysmal atrial fibrillation

Introduction Ablation index (AI)‐guided radiofrequency ablation has been increasingly used for the treatment of drug‐resistant paroxysmal atrial fibrillation (AF)，but the optimal AI targets remain to be determined. We aimed to examine the efficacy and safety of catheter ablation guided by moderate AI values but more strict procedural endpoints in patients with paroxysmal AF. Methods We conducted a retrospective review of a consecutive series of...
