The unipolar epicardial auriculogram was able to characterize the complexity of the postoperative fibrillatory process and also to identify patients with a high risk of late recurrence. Auriculogram type III had a low success rate for the intraoperative ablation procedure. The lines of the ablation procedure facilitated organization of the auriculograms.

Venous wall invasion seems to be related with a greater incidence of lymph node disease, but these patients are candidates to intention-to-cure radical surgery. Thrombus level is not a prognostic factor per se, but it should be taken into consideration for surgical planning. After radical surgery survival rates achieved are similar to those of tumors without venous thrombus.
