Adding surgical atrial fibrillation ablation during mitral valve surgery improves 1-year freedom from AF but increases the need for permanent pacemakers.
The addition of atrial fibrillation ablation to mitral-valve surgery significantly increased the rate of freedom from atrial fibrillation at 1 year among patients with persistent or long-standing persistent atrial fibrillation, but the risk of implantation of a permanent pacemaker was also increased.
