Concomitant off-pump modified maze and coronary surgery.

We describe a modification of the Cox-Maze III using bipolar radiofrequency combined with off-pump coronary artery surgery for the treatment of patients with coronary artery disease and long-standing permanent atrial fibrillation. This study reports the midterm outcome of 12 patients with coronary artery disease and long-standing permanent atrial fibrillation who underwent off-pump coronary artery surgery and concomitant modified Maze with bipolar radiofrequency. At a mean follow-up of 23 months, all patients were alive, and 75% (9 of 12) had sinus rhythm. Our modified Maze can be safely and effectively combined with coronary artery surgery in an off-pump setting.
