Brief Summary:
The purpose of this study is to demonstrate the safety and effectiveness of the CardioFocus Endoscopic Ablation System with Adaptive Contact (HeartLight) in the treatment of atrial fibrillation by creating electrical isolation of the pulmonary veins.

Condition or disease Intervention/treatment Phase
Paroxysmal Atrial Fibrillation Device: EAS-AC (HeartLight) Procedure: Control Arm Ablation Phase 3

Detailed Description:
A randomized, controlled trial designed to demonstrate the safety and effectiveness of the experimental device to deliver pulmonary vein isolation as a treatment for symptomatic atrial fibrillation.

Primary Outcome Measures :
  1. Number of Participants That Meeting the Efficacy Success Criteria as Described in the Outcome Measure Description [ Time Frame: 1 year ]
    Episodes of AF were monitored during the follow-up period and the rate of participants with no documented, symptomatic episodes of AF in follow-up were be compared. Other efficacy success/failure criteria included acute isolation of all clinically relevant pulmonary veins, lack of ablation-induced left atrial flutter, use of AADs during a follow-up period and left heart ablation or implant for AF in follow-up. Randomized and treated participants that were evaluable for efficacy are reported on for the Outcome Measure.
