All CB procedures in this study were performed using the FlexCath Advance™ and the Arctic Front Advance Pro™, Medtronic, Dublin, Ireland. The CB was placed in each PV antrum under fluoroscopy guidance. Optimal PV occlusion by CB was evaluated via contrast medium application. To obtain PV signals and to assess electrical isolation, a decapolar circumferential mapping catheter (Achieve™ and Achieve Advance™ Mapping Catheters, Medtronic) was used. The freeze duration was determined by either the observed time to isolation (TTI; in case of visible PV signals) or achieved nadir temperature during the applied freeze [16 (link), 17 (link)]. During CB-PVI of the right PVs, continuous phrenic nerve pacing was performed to avoid phrenic nerve palsy. The endpoint for CB procedures was proof of entrance block using the Achieve mapping catheter.

For cryoballoon PVI, a 28-mm cryoballoon (Arctic Front Advance Pro™, Medtronic, Dublin, Ireland or POLARx™, Boston Scientific, Marlborough, MA, USA) was applied. The workflow of a cryoballoon PVI has been previously described in detail [4] . Briefly, the balloon was inserted through a steerable sheath (15Fr FlexCathAdvance™, Medtronic or 15.9Fr POLARSHEATH™, Boston Scientific). The cryoballoon was placed in each PV antrum under fluoroscopy guidance, and PV occlusion was verified via contrast agent application. PV potentials were recorded using a 20-mm circular inner lumen mapping catheter with 8 electrodes (Achieve™ and Achieve Advance™ Mapping Catheters, Medtronic or POLARMAP™, Boston Scientific). The duration of cryoablation was determined by either the observed time-to-isolation (TTI; in case of visible PV signals) or achieved nadir temperature [11] .
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
