Atrial Fibrillation Recurrence After Cryoballoon Ablation

Not Applicable

Completed

• Conditions: Atrial Fibrillation
• Interventions: Other: Use of the Achieve catheter followed by ICE-guided mapping catheter

• Registration Number: NCT01772030
• Lead Sponsor: University of Pittsburgh

Brief Summary

The purpose of the study is to evaluate the mechanisms of recurrent atrial fibrillation after cryoballoon ablation using the Arctic Front Ablation System. For those with pulmonary vein reconnection, specific sites of reconnection will be evaluated with left atrial intracardiac echo (ICE) guidance. The Achieve mapping catheter will be evaluated head-to-head with our current method of ICE-guided recordings from a conventional mapping catheter with high output pulmonary venous pacing.
