Background Catheter ablation (CA) for symptomatic atrial fibrillation (AF) offers the best outcomes for patients. Despite the benefits of CA, a significant proportion of patients suffer a recurrence; hence, there is scope to potentially improve outcomes through technical innovations such as ablation index (AI) guidance during AF ablation.

Pulsed Field Ablation is a relatively new modality for treatment of atrial fibrillation. In conventional ablation for atrial fibrillation, either heating of tissue is produced by radiofrequency application or freezing of tissues by cryoablation. Pulsed field ablation group had 305 patients while thermal ablation group had 302 patients.
