  Purpose

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.

Paroxysmal Atrial Fibrillation
Device: HD Mesh Ablation System
Drug: Anti-arrhythmic drugs
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Single Blind (Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Randomized Controlled Trial of Radiofrequency Ablation for the Treatment of Paroxysmal Atrial Fibrillation Using the Bard High Density Mesh Ablation System (MAGELLAN)

Primary Outcome Measures:
  • Number of Participants With Major Complications [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
    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.

  • Number of Participants With Serious Atrial Fibrillation Events [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
    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.

  • Number of Participants With Freedom From Symptomatic Atrial Fibrillation [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    Due to the early termination and the enrollment of only seven randomized patients, the endpoint was not evaluable.


Secondary Outcome Measures:
  • Number of Participants With the Occurrence of Pulmonary Vein Stenosis in Mesh Treated Patients. [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
    Defined as a greater than or equal to 70% diameter reduction in a pulmonary vein compared with the baseline measurement as assessed by an independent core imaging laboratory.

  • Number of Participants With Acute Procedural Success in Mesh Treated Patients. [ Time Frame: During the mesh ablation procedure ] [ Designated as safety issue: No ]
    Acute procedural success was defined as the ability to isolate 3 of 4 pulmonary veins with the mesh ablation system alone without the need for further ablation with a distal tip catheter
