Comparison of Pulmonary Vein Isolation Plus Additional Catheter Ablation or Pulmonary Vein Isolation Alone for the Treatment of Atrial Fibrillation for Patients With Paroxysmal Atrial Fibrillation: A Prospective, Randomized Study
There is a need to compare the efficacy of PVI versus PVI plus catheter ablation, which
includes ablation of complex fractionated atrial electrograms (CFAE) and linear lesions in
the same procedure. If it is found that the PVI alone is as effective as PVI plus catheter
ablation of CFAE and linear lesions, it may reduce the need for catheter ablation.

of onset (PAF) Failed or refractory to one AAD (class I and/or III)
- Provided written informed consent
- Be eligible for an AF ablation procedure for Paroxysmal AF
(Step 2 - Randomization)
