Summary

Pulmonary vein isolation (PVI) using cryoballoon ablation is a well-established procedure for the treatment of atrial fibrillation (AF). However, the use of cryoballoon ablation in recent clinical trials have been limited to PVI. As such, patients with paroxysmal AF have been the main recipients of this procedure. In patients with persistent AF, or patients with paroxysmal AF and significant AF substrate other than the pulmonary veins, the utility of cryoballoon ablation is less straightforward. In such patients, the choices are to either use cryoballoon ablation in a PVI-only approach or alternatively, use cryoballoon ablation for PVI followed by the use of radiofrequency ablation for additional ablation and/or substrate modification.

Substrate modification by targeting left atrial fibrosis detected on delayed enhancement magnetic resonance imaging (DE-MRI) is an increasingly popular approach with growing data showing its utility to decrease the risk of recurrence. The ability to use cryoballoon ablation for fibrosis based ablation in addition to PVI will therefore provide a significant advantage.

This study will evaluate feasibility and the outcome of targeted ablation of left atrial fibrosis detected on DE-MRI in addition to pulmonary vein isolation using the Arctic Front Advance Cryoballoon Catheter.
