Does Surgical Ablation Energy Source Affect Long-Term Success of the Concomitant Cox Maze Procedure?
Ad and colleagues compared outcomes in patients receiving a Cox Maze (CM) procedure with cryothermal energy only or with cryothermal and bipolar radiofrequency, with 298 patients in each group. CM performed with either energy source proved safe and effective, with the authors evaluating perioperative outcomes, rhythm status, survival, and clinical events. Cryothermal ablation alone was associated with reduced perioperative stroke incidence and higher rates of sinus rhythm out to 60 months follow-up, findings that the authors highlight as important for future study.
