Surgical maze procedures have a high success rate, with from 70% to 95% of people being free of atrial fibrillation long term after the procedure. Some people may still need medications to help control their irregular heart rhythm after the procedure. If your atrial fibrillation returns, you may need another catheter ablation or other treatment.

If you develop a slow heart rhythm after your maze procedure, your doctor may suggest you have a pacemaker implanted.
