Use of a High Density Mapping System to Complete Wide Area Circumferential Ablation of the Pulmonary Veins and Avoid Ostial Segmental Ablation

Stopped Recruitment issues due to competing studies. Higher than expected PVI on first pass. Sample would have to be increased which was not feasible.

Conditions

• Atrial Fibrillation

Interventions

• PROCEDURE: Atrial Fibrillation Ablation
• DEVICE: Catheters used to isolate pulmonary veins
• PROCEDURE: Atrial Fibrillation Ablation with HD mapping to isolate PVs
• DEVICE: Rhythmia HD mapping
