Why the study?
Does pulsed-field ablation improve freedom from atrial tachyarrhythmia at 1 year compared to cryoballoon or radiofrequency ablation in patients with paroxysmal atrial fibrillation?
Does pulsed-field ablation improve freedom from atrial tachyarrhythmia at 1 year compared to cryoballoon or radiofrequency ablation in patients with paroxysmal atrial fibrillation?
Pulsed-field ablation appears to be as effective as cryoballoon or radiofrequency ablation for achieving 1-year freedom from atrial tachyarrhythmias in patients with paroxysmal atrial fibrillation.
PFA may be comparable to CBA or RFA for 1-year ATa freedom in paroxysmal AF; leaves open need for randomized confirmation.
In a propensity score matched analysis of patients with paroxysmal AF, freedom from any ATa 1 year after PVI using PFA was favourable and at least as good as for PVI with CBA or RFA.
