Summary

This chapter discusses cryoballoon pulmonary vein isolation for atrial fibrillation. For treating the pulmonary vein antrum with a single-shot strategy independent of the particular anatomy, the steerable cryoballoon Arctic Front™ (Medtronic CryoCath ) was developed in 2005 with both 23 mm and 28 mm balloon diameters. The chapter focuses on functions of the Arctic Front cryoballoon. Transmural freezing of the complete surface of the pulmonary vein antrum can possibly better fulfill the dream of persistent pulmonary vein isolation by a low-risk procedure as first-line therapy than point-to-point radiofrequency (RF) ablation. Desirable advancements in balloon system design include a higher ratio of cooling power to balloon size as well as more homogeneous cooling of the balloon surface, which would facilitate the ablation of crosstalk, inferior reconduction, and gaps.
