PVAC case requiring surgical intervention. One case each of phrenic nerve palsy, right leg numbness (due to local infiltration of local anaesthetic around the femoral nerve) and air embolism were associated with cryoablation. All resolved within hours, did not require intervention and did not delay discharge. No long-term sequelae were seen. Conclusions PVAC and cryoballoon AF ablation appear equally efficacious with similar procedure times in an unselected population. Both were associated with a low adverse event rate.
