ABSTRACT Introduction Pulmonary vein isolation (PVI) using a cryoballoon is well-established for the treatment of paroxysmal atrial fibrillation (PAF). Compared to other available technologies, the usage of a stable, low-pressure cryoballoon (POLARx, Boston Scientific) has demonstrated lower nadir temperatures and longer thawing times.
