Blackstone, and Michael Argenziano for the CTSN Investigators

Patients with persisent or long-standing atrial fibrillation requiring mitral valve surgery were randomized to either surgical ablation or no ablation.  Surgical ablation patients were further randomized to pulmonary vein isolation or biatrial MAZE.  More surgical ablation patients were free from atrial fibrillation than control.  There was no difference in atrial fibrillation in pulmonary vein isolation vs. biatrial MAZE.
