If you develop a slow heart rhythm after your maze procedure, your doctor may suggest you have a pacemaker implanted. If your atrial fibrillation returns, you may need another catheter ablation or other treatment. Some people may still need medications to help control their irregular heart rhythm after the procedure. 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 patients may be treated with a robot-assisted catheter ablation procedure called a mini-maze. While you are on the bypass machine, your doctor may also do other needed cardiac surgeries, such as valve repair or pacemaker placement. Scar tissue forms where the lines are created. He or she will use energy - such as heat, cold or laser - or a scalpel to create the pattern of lines. Then, your doctor will make an incision in your chest and access the upper chambers of your heart. During the procedureįor the surgical maze procedure, you will be put to sleep with general anesthesia and placed on a heart-lung bypass machine.

In these cases, the maze procedure is done during open-heart surgery. The maze procedure is the preferred method of atrial fibrillation treatment if you also need another heart surgery, such as for coronary artery bypass or valve repair. The maze procedure is done to correct atrial fibrillation and improve the quality of life of people with this condition. Because scar tissue doesn't carry electricity, the maze interferes with stray electrical impulses that cause atrial fibrillation. ![]()
