Cardiac surgeons often encounter atrial fibrillation in patients referred for other cardiac surgical procedures. However, surgical ablation of atrial fibrillation continues to be undertreated at the time of cardiac surgery. Recent data have supported high rates of sinus rhythm restoration and a survival advantage for concomitant treatment of atrial fibrillation during cardiac surgery. Unfamiliarity with recommended lesion sets, energy sources, available devices, and techniques has resulted in an underutilization of the Maze procedure.

Learning Objectives
Upon completion of this activity, participants should be able to:

  • Explain the different energy sources for performing the Maze procedure
  • Discuss the available devices for surgical ablation and left atrial appendage ligation
  • Perform the Maze IV procedure lesions based on different operative scenarios (mitral valve surgery, coronary artery bypass grafting, aortic valve replacement)
  • Describe the Cut and Sew Maze procedure
