Oral anticoagulation therapy was administered for at least 3 weeks before the ablation procedure and transesophageal echocardiography was performed within 3 day of the procedure to exclude atrial thrombus. All signals were stored on a recorder system (Labsystem Pro, Bard Electrophysiology, Lowell, MA, USA). Ablation and mapping accesses were established through bilateral femoral veins. Then, a decapolar catheter (2-8-2 mm interelectrode distance) was placed with its 9–10 electrodes at the CS ostium (CSO) through the left common femoral vein or the left subclavian vein. After the administration of intravenous heparin to reach an activated clotting time of 250–350 s, the LA was accessed using a 3.5 mm cold salt water-irrigated ablation catheter (Smarttouch SF) (Biosense Webster Inc.) and a multi-polar mapping catheter (PentaRay—20 electrodes with 2-6-2 mm spacing) via double trans-septal punctures through the right common femoral veins under fluoroscopy. Electroanatomic maps including anatomical maps, activation maps, and Bipolar maps were obtained with the 3-dimensional electroanatomic mapping system (CARTO 3; Biosense Webster, Diamond Bar, CA).

Radiofrequency procedures were performed using a three-dimensional (3D) mapping system (CARTO3, Biosense Webster, Irvine, CA, USA) in combination with a contact force-sensing ablation catheter (Smarttouch SF, Biosense Webster) and a high-density multipolar mapping catheter (Pentaray, Biosense Webster). A steerable sheath was used (Destino Reach, Oscor, Palm Harbor, FL, USA). Ablation was performed by adhering to the CLOSE protocol.13 (link) Pulmonary vein isolation was verified by 3D mapping at the end of the procedure.

Radiofrequency procedures were performed using a 3D mapping system (CARTO3, Biosense Webster, Irvine, CA, USA) in combination with a CF-sensing ablation catheter (Smarttouch SF, Biosense Webster, Irvine, CA, USA) and a high-density multipolar mapping catheter (Pentaray, Biosense Webster, Irvine, CA, USA). A steerable sheath was used (Destino Reach, Oscor, Palm Harbor, FL, USA). Ablation was performed by adhering to the CLOSE protocol [5 (link)]. Power settings were at the discretion of the operator and ranged from 30 to 50 Watts. PVI was verified by 3D mapping at the end of the procedure.

The electrophysiology study was performed under general anesthesia. Through the femoral vein, one decapolar catheter was placed in the coronary sinus and transseptal puncture was performed to advance the mapping and ablation catheters to the left atrium (LA). All patients underwent electroanatomical (EA) mapping during sustained AF (20 (link)). The EA mapping and signal acquisitions were performed using a 20-pole multi-electrode catheter (PentaRay, Biosense Webster, Diamond Bar, CA, USA) and tissue proximity index (TPI) active during all the procedures. For the ablation, an irrigated contact-force sensing catheter was used (SmartTouch, or SmartTouch SF, Biosense Webster, Diamond Bar, CA, USA). The ablation targeted a wide area around the PVs antra to achieve pulmonary vein isolation (PVI); additional lesions were delivered at the carinas. Ablation lesions were guided by the Ablation Index (CARTO3 V7, Biosense Webster, Diamond Bar, CA, USA), targeting values of 350 or 450 units at the posterior or anterior left atrial wall, respectively (21 (link)). Radiofrequency power was set at 35–50 W at the anterior aspect of the veins and 25–45 W at the posterior aspect, with an irrigation flow of 30 ml/min using power control mode.
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.
