Persistent Atrial Fibrillation
Conditions
Brief summary
The purpose of this feasibility study is to further explore characteristics of ablation targets identified by CARTOFINDER 4D LAT Algorithm in subjects with persistent atrial fibrillation and to assess the acute outcome of CARTOFINDER Guided Ablation in terms of the termination of atrial fibrillation to either Normal Sinus Rhythm or Atrial Tachycardia.
Interventions
All enrolled subjects who have ablation targets identified will undergo CARTOFINDER guided ablation (CFGA) followed by PVI. Subjects will be followed per the protocol schedule. Subjects who have no ablation target identified on the baseline CARTOFINDER map will undergo ablation per the institution's standard of care and be followed for 7 days for safety monitoring, then exit from the study.

Eligibility
Inclusion criteria
Subjects must meet the following inclusion criteria: 1. Age \> 18 years. 2. Patients who have signed the Patient Informed Consent Form (ICF) 3. Scheduled to undergo a clinically-indicated catheter ablation procedure for treatment of persistent atrial fibrillation (defined as continuous atrial fibrillation that is sustained beyond seven consecutive days). 3.1. Drug-refractory atrial fibrillation. (failed 1 or more class I or III antiarrhythmic drugs) and demonstrating Persistent AF (requiring drugs or electrical shock to terminate) 4. Able and willing to comply with all pre-, post-, and follow-up testing and requirements (e.g. patients not confined by a court ruling)
