  • Patients who have an active infection or sepsis
  • Patients who have uncorrected reversible cause(s) of AF
  • Patients who are contraindicated for anticoagulants
  • Patients who are being treated for arrhythmias other than AF
  • Patients who have had any previous AF or left atrial catheter ablation
  • Current participation in another clinical investigation of a medical device or a drug, or recent participation in such a study within 30 days prior to study enrollment.

Outcomes

Primary Outcome Measures

AF free off all Class I and III Anti Arrhythmic Drugs (AADs).
The primary efficacy data will be an evaluation of the number of subjects free from AF and free of all Class I and III Anti Arrhythmic Drugs (AADs) from 3 months through 12 months post procedure.

Secondary Outcome Measures

AF free regardless of the Class I and III AADs status
The secondary efficacy data will be an evaluation of the number of subjects free from AF regardless of their Class I and III AADs status from 3 months through 12 months post procedure.

Brief Summary
This is a multi-center, prospective, open label, feasibility clinical study,evaluating the safety and efficacy of the combined ablation procedure for the treatment of symptomatic paroxysmal atrial fibrillation.
Detailed Description
The purpose of this feasibility study is to evaluate the safety and efficacy of the epicardial / endocardial combined procedure for the treatment of drug refractory symptomatic Paroxysmal Atrial Fibrillation (AF) patients, using the nContact Numeris®-AF Guided Coagulation System with VisiTrax® epicardially and the Biosense Webster NaviStar® ThermoCool® Diagnostic/Ablation deflectable Tip Catheter in conjunction with the Carto Navigation System endocardially.
