NCT00741611

Brief Summary

This is a randomized controlled study of the Bard High Density Mesh Ablation System for treatment of paroxysmal atrial fibrillation. This study will determine if the HD Mesh Ablation System is as safe as and more effective than anti-arrhythmic drugs.

Outcome Measures

Primary Outcomes (3)

  • Number of Participants With Major Complications

    A Major Complication was defined as any adverse event that met the following criteria: 1) event was a Serious Adverse Event; 2) event was related to study device (mesh/mesh toolkit) or study procedure and 3)event was a) a cardiovascular adverse event occurring within 7 days of the procedure and/or b) a direct ablation effect adverse event occurring within 12 months of the study procedure.

    12 months

  • Number of Participants With Serious Atrial Fibrillation Events

    Due to the early study termination and the small number of randomized patients (seven), this primary endpoint analysis (comparison of the rate of events in the mesh group to the rate in the drug group) could not be performed. Counts of events occurring in the 36 treated patients are reported by study group instead.

    12 months

  • Number of Participants With Freedom From Symptomatic Atrial Fibrillation

    Due to the early termination and the enrollment of only seven randomized patients, the endpoint was not evaluable.

    12 months

Secondary Outcomes (2)

  • Number of Participants With the Occurrence of Pulmonary Vein Stenosis in Mesh Treated Patients.

    12 months

  • Number of Participants With Acute Procedural Success in Mesh Treated Patients.

Limitations and Caveats

Due to the study's early termination and enrollment of only 7 randomized patients, predefined study endpoints were not evaluable. Treated patients were followed through 12 months postprocedure and data were summarized where possible.
