Mechanisms and Patterns of Atrial Fibrillation Recurrence After Cryoballoon Ablation
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.
