Best practice guide for cryoballoon ablation in atrial fibrillation: The compilation experience of more than 3000 procedures.

BACKGROUND

Since the release of the second-generation cryoballoon (CB2; Arctic Front Advance(TM), Medtronic Inc) and its design modifications with improved cooling characteristics, the technique, dosing, and complication profile is significantly different from that of the first-generation cryoballoon. A comprehensive report of CB2 procedural recommendations has not been reported.

OBJECTIVE

The purpose of this study was to review the current best practices from a group of experienced centers to create a user's consensus guide for CB2 ablation.

METHODS/

RESULTS

High-volume operators with a combined experience of more than 3000 CB2 cases were interviewed, and consensus for technical and procedural best practice was established.

CONCLUSION

Comprehensive review of the CB2 ablation best practice guide will provide a detailed technique for achieving safer and more effective outcomes for CB2 atrial fibrillation ablation.
