AF, atrial fibrillation; LIPV, left inferior pulmonary vein; LSPV, left superior pulmonary vein; PV, pulmonary vein; PVI, pulmonary vein isolation; RIPV, right inferior pulmonary vein; RSPV, right superior pulmonary vein.

^aFollow-up was performed by confirming available data obtained from routine practice at the 12-month (±30 days) post-operative visit. Mid-term data are from Day 91 after the procedure.

^bDenominator was the number of patients who underwent a repeat ablation procedure.

^cDenominator was the number of repeat ablation procedures.

^dPercentage was calculated as (number of PVs re-isolated amongst targeted PVs at repeat procedure/number of all targeted PVs at repeat procedure) × 100.

^ePercentage was calculated as (number of repeat ablation procedures identifying new foci outside of the initially isolated area amongst repeat ablation procedures/number of all repeat ablation procedures) × 100.
