TL;DR: Circumferential PVI using the novel compliant endoscopic ablation system was feasible in the majority of left PVs and minority of right PVs accompanied by a complication rate comparable to established approaches.

TL;DR: Although there was a trend for more recurrences and complications in the RF group, a more favourable risk profile in patients undergoing CB ablation might have biased the results.

TL;DR: Second-generation cryoballoon atrial fibrillation ablation is associated with a high rate of durable PVI in patients with ATa recurrence and the RSPV represents the PV with the greatest risk for left atrium-pulmonary vein reconnection.

TL;DR: The following review will introduce the basic principles of the systems, give an insight into the merits and demerits of remote navigation, and will further focus on the initial clinical experience at the centre with focus on pulmonary vein isolation (PVI) procedures.

TL;DR: Second-generation cryoballoon demonstrated a high rate of acute PVI in a significant faster procedure, which also utilized less radiation exposure and less dual-balloon usage during an average procedure, and the safety profile remains favourable with a non-significant trend for more phrenic nerve palsies.
