Compare the efficacy of the left atrial Cox-Maze IV lesion set versus the Tampa 2 lesion set versus the EnCompass ablation alone, in the surgical treatment of atrial fibrillation at one year post-operatively.
This is a single center prospective, randomized trial to compare the outcomes, specifically the freedom from atrial fibrillation at one year, and possibly up to five years, of three different approaches to the cardiac surgical management of atrial fibrillation. Several strategies to accomplish surgical ablation are acceptable and have been shown retrospectively to be successful. The Cox-Maze bi-atrial, left and right atrial lesions, ablation (whether III or IV) remains the gold standard by which all surgical ablations are compared. Further refinement in ablation technology and research has fu…
