NCT00431834

Brief Summary

This investigation is a prospective, nonrandomized multicenter clinical trial evaluating the outcome of patients with atrial fibrillation (AF) requiring concomitant open heart surgery plus the Cardioblate Surgical Ablation System using the modified Maze III procedure. The trial population includes patients requiring valve replacements or repairs, atrial septal defect (ASD) repairs, patent foramen ovale (PFO) closure or coronary artery bypass graft (CABG) procedures. The study objectives are to demonstrate that the Medtronic Cardioblate Surgical Ablation System can safely and effectively treat permanent AF patients.

Outcome Measures

Primary Outcomes (2)

  • Efficacy Endpoint: The Percent of Patients Off Class I and/or III Antiarrhythmic Drugs and Out of Atrial Fibrillation as Determined by 24 Hour Holter Recording Conducted at 6 Months Postoperatively.

    Subject's heart rhythm was evaulated by wearing a Holter Monitor for 24 hours.

    6 months

  • Safety Endpoint: Composite Acute Major Adverse Event Rate, Within 30 Days Post-procedure or Hospital Discharge

    Major Adverse Events included: mediastinitis, death, myocardial infarction, stroke, transient ischemic attacks (TIA), pulmonary embolism, peripheral arterial embolism, and esophageal injury.

    30 days post procedure or hospital discharge

Secondary Outcomes (2)

  • Efficacy Endpoints: The Percent of Patients Out of AF, Regardless of Antiarrhythmic Drug Status, as Determined by a 24 Hour Holter Recording at 6 Months

    6 months

  • Safety Endpoints: Composite 6-month Major Adverse Event Rate, Post-procedure

    6 months
