A venous access site in the right internal jugular vein was used to introduce a duo‐decapolar catheter (Bee‐AT, Japan‐Lifeline Co., Ltd., Tokyo, Japan), of which the distal 10‐poles were positioned in the coronary sinus while the proximal 10‐poles were placed along the crista terminalis for internal cardioversion. After a double transseptal puncture, a 20‐pole circular mapping catheter (Optima™ or Reflexion HD™; St. Jude Medical, St. Paul, MN) and irrigated‐tip ablation catheter (Cool Flex™ or FlexAbility™; St. Jude Medical) were inserted into the LA for the mapping and ablation. A 3D geometry of the LA was created and fused with the pre‐operative 3DCT using an EnSite NavX™ system (St. Jude Medical). A temperature monitoring probe (SensiTherm™; St. Jude Medical) was inserted into the esophagus.

Pulmonary vein isolation (PVI) was performed using one 7-F decapolar circular catheter (Optima; St. Jude Medical, Inc.) positioned at the ostia of ipsilateral PVs; 3D-CT reconstruction was integrated into an electro-anatomical mapping system (EnSite NavX system, St. Jude Medical, Inc.). We created bilateral circular lesions with wide-area circumferential ablation encircling the ipsilateral PV; each application of RF energy was delivered for 30–60 by using a 3.5-mm irrigated tip RF catheter (FlexAbility; St. Jude Medical, Inc.), with the temperature limited to 42℃, power output at 25–35 W, and a flow rate of 13 mL/min. Biphasic direct current cardioversion restored the SR if AF did not terminate spontaneously after successful PVI. The endpoint of PVI was the creation of a bidirectional conduction block between LA and PVs
20) . At the end of the procedure, all PVs were successfully isolated.

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.
