ALAL, additional left atrial lesions; BCL, bilateral caval connecting line; Box, box lesion set; CTI, cavotricuspid isthmus; GP, ganglionated plexus; IVC, inferior vena cava circumferential lesion; LAA, left atrial appendage; LOM, ligament of Marshall; MIL, mitral isthmus lesion; N, no; Pts, patients; PVI, pulmonary vein isolation; R, right [22]; RF, radiofrequency; SVC, superior vena cava circumferential lesion; VATS, video-assisted thoracoscopic surgery; Y, yes.

^a(n) is specified when not all patients received a particular ablation line.

^b13 patients had an additional superior pulmonary vein connecting line and an unspecified subset of those also had an inferior pulmonary vein connecting line.

^cGP was presumably taken with epicardial fat removal prior to ablation with the unipolar probe. Removal was not confirmed.

^dWhen firing foci were identified within the pulmonary veins, an additional pulmonary vein antral line was performed even in the presence of an effective box lesion [24].

Additional lines were also made to target complex atrial fractionated electrograms [6].
