Expanding the potential patient population for pulsed field ablation, results from the SINGLE SHOT CHAMPION study suggest PFA might be just as good as cryoballoon ablation for patients with paroxysmal AFib. PFA has shown advantages in procedure time and safety, but its effectiveness is unproven compared to cryoballoon ablation.
