Vagal impact of cryoballoon ablation during pulmonary vein isolation

Atrial fibrillation (AF) is the most common cardiac arrhythmia, resulting in hemodynamic abnormalities and thromboembolic events. The prevalence of AF is around 1% in the general population, increasing with age. It results in a 5-fold increased risk of ischemic stroke, 3-fold increased risk of heart failure, and 2-fold increased risk of both dementia and mortality. Hassaiguerre et al. [1] and Chen et al. [2] firstly reported the dominant and pathologic role of pulmonary vein (PV) triggers as being responsible for the arrhythmogenesis of AF.
