Maze Procedure for Atrial Fibrillation

The maze surgical procedure is a treatment for atrial fibrillation or Afib, a type of irregular heartbeat (arrhythmia). During the procedure, a surgeon makes small incisions on the upper chambers of the heart in a maze-like pattern. The incisions create scar tissue that will block the electrical signals causing the irregular heartbeat.

Your surgeon makes the cuts using very hot or cold applications from radio waves, freezing, microwaves or ultrasound energy. The maze procedure can be completed through small cuts in the chest or during open-heart surgery. It is often done at the same time a person is having coronary artery bypass or valve repair surgery.

The maze procedure has proven to be very successful in treating patients with atrial fibrillation – stopping the problem in about nine out of 10 people. A patient may need to take heart rhythm medicine after the procedure.
