Introduction: Robotic cryothermic Cox-Maze (CM) IV is a minimally invasive procedure that reliably replicates the biatrial lesion set of the CM III by utilizing cryothermia as a single power source. Methods: Herein we describe a step by step creation of the biatrial CM III lesion sets utilizing the minimally invasive robotic platform. Results: Technical details are reviewed for this single incision, single stage, highly effective option for stand-alone or concomitant surgical ablation of atrial fibrillation (AF). Conclusion: Robotic cryothermic CM IV can be safely performed as a stand-alone or concomitant procedure, and offers a comprehensive surgical ablation solution for patients with AF.
