Brief Summary:
A prospective, multicenter, randomized study to assess the safety and effectiveness of FIRM-guided procedures in conventional "redo" RF ablation procedures for the treatment of persistent and paroxysmal atrial fibrillation.

Condition or disease Intervention/treatment Phase
Persistent Atrial Fibrillation Paroxysmal Atrial Fibrillation Procedure: Standard PVI Procedure: FIRM-Guided Procedure and PVI Not Applicable

Detailed Description:

The hypothesis of this study was that Focal Impulse and Rotor Modulation (FIRM) guided procedures will eliminate the source of clinical arrhythmias in subjects with clinical indications for repeat AF ablation procedures.

This study is a prospective, multicenter, randomized, controlled study to assess the safety and effectiveness of FIRM procedures followed by ablation including pulmonary vein isolation versus a standard conventional procedure including pulmonary vein isolation for the redo-treatment of persistent or paroxysmal atrial fibrillation after one failed previous pulmonary vein isolation.

Primary Outcome Measures :
  1. Freedom from atrial fibrillation atrial fibrillation (AF), atrial tachycardia (AT), or atrial flutter (AFL) recurrence at 12 months post procedure. [ Time Frame: 12 months post procedure ]
    Single procedure freedom from recurrence from 3-12 months post procedure

  2. Freedom from serious adverse events related to the procedure [ Time Frame: 10-day post procedure ]
    Freedom from any procedure-related serious adverse event from 0-10 days post procedure

  3. Freedom from serious adverse events related to the procedure [ Time Frame: 12-month post procedure ]
    Freedom from any procedure-related serious adverse event from 0-12 months post procedure
