The Impact of Expandable Cryoballoon on Autonomic Control of the Heart

Status Recruiting

Clinical Trial Summary

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 plexi) might enhance this beneficial modulation of the autonomic system of the heart. This study intends to compare the effects of cryoablation employing expandable balloon (POLARxFIT) vs. standard balloon (POLARx) on autonomic system of the heart.
