About This Trial
Approximately 40% of patients following cryoballoon ablation show signs of parasympathetic denervation. The presence of such effect is related to better outcomes in terms of clinical efficacy (freedom from atrial fibrillation). It could be hypothesized that larger sized balloon (POLARxFIT system) because of more antral position within the left atrium (and hence smaller distance from ganglionated p…
