ABLATE is a prospective, non-randomized multi-center clinical trial to demonstrate the safety and effectiveness of the AtriCure Bipolar System for treating permanent atrial fibrillation during concomitant on-pump cardiac surgery.

Condition Intervention Phase
Atrial Fibrillation Device: AtriCure Bipolar System Phase 3

Primary Outcome Measures:
  • Percent of Patients Free From AF and Off Class I and III Anti-arrhythmic Drugs as Determined by Holter Monitoring at 6 Months. [ Time Frame: 6 Months Post Procedure ]
  • Composite Acute Major Adverse Event Rate, Within 30 Days Post-procedure or Hospital Discharge [ Time Frame: 30 days Post Procedure ]
    Major Adverse Events consist of Death within 30 days or beyond 30 days if considered device related, Excessive Bleeding, Stroke, TIA or MI. A clinic visist was performed at 30 days to fully assess the patient for adverse events.

Secondary Outcome Measures:
  • Percent of Patients Free From AF, Independent of Antiarrhythmic Drug Status as Determined by Holter Monitoring at 6 Months. [ Time Frame: 6 Months Post Procedure ]
  • Composite 6-month Post-procedure Major Adverse Event Rate. [ Time Frame: 6 Months Post Procedure ]

Enrollment: 55
Study Start Date: November 2007
Study Completion Date: December 2012
Primary Completion Date: December 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: AtriCure Bipolar System
The AtriCure Synergy Bipolar Ablation system is used to create lesions outlined in the Maze IV procedure during a concomitant open cardiac surgical procedure.
Device: AtriCure Bipolar System
Surgical bipolar radiofrequency ablation using the AtriCure Bipolar System
