(n) is specified when not all patients received a particular ablation line.
Additional lines could be made to the aortic trigone (10 patients), or a roof line (17 patients) could be created, all at the discretion of the surgeon.
This varied by center. At 1 hospital, only right-sided GP were ablated and the LOM was cut. At another center, bilateral GP were ablated but the LOM was left alone. ALAL, additional left atrial lesions; Box, box lesion set; GP, ganglionated plexus; LAA, left atrial appendage; LOM, ligament of Marshall; PVI, pulmonary vein isolation; VATS, video-assisted thoracoscopic surgery; N, no; Y, yes; NS, specific number not specified.
