Atrial Fibrillation Recurrence After Cryoballoon Ablation

This study is ongoing, but not recruiting participants.

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.

Condition Intervention
Atrial Fibrillation
Other: Use of the Achieve catheter followed by ICE-guided mapping catheter

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: No masking
Primary Purpose: Diagnostic
Official Title: Mechanisms and Patterns of Atrial Fibrillation Recurrence After Cryoballoon Ablation
