Spontaneous and Adenosine‐Induced Pulmonary Vein Reconnection After Cryoballoon Ablation with the Second‐Generation Device

Abstract

The incidence of spontaneous and adenosine-induced PV reconnection following ablation with the novel CB-Adv is very low occurring in 4% of initially isolated veins. Nadir temperature <-51 °C and rewarming time >28 seconds identified absence of acute reconnections, thus avoiding prolonged waiting time and adenosine challenge in such cases.
