Why is this procedure done?
The heart has an electrical system that sends signals to the heart. These tell the heart to beat and contract in a normal pattern. If the pattern is not normal or regular, it is an arrhythmia. Your heart may beat faster or slower than normal. ‚
Arrhythmia may be due to abnormal electrical activity in the heart. If this condition is not treated the right way, it may cause health problems like: ‚
- Less blood flow
- Stroke
- Weakened heart
- Blood clot
- Irregular heartbeat
Atrial fibrillation is a kind of arrhythmia in which the heart beats irregularly. This may cause blood to collect in the heart. If the collected blood does not move because the heartbeat is not regular, a blood clot may form. Blood clots block off blood flow to parts of the body like the heart, brain, and legs. ‚
Maze is a surgery done to treat atrial fibrillation. The surgery is done to make your heartbeat regular. You may need Maze surgery if you have not responded to other types of treatment or are at a higher risk for stroke. In some cases, the doctor puts a pacemaker underneath your skin at the same time. This will help control your heartbeat. ‚
Some doctors can do this surgery with smaller cuts, called minimally invasive surgery. This procedure uses special tools and small surgical cuts. This avoids problems of an open surgery like a long healing period and more pain. ‚

What happens during the procedure?
- Once you are in the operating room, you will be given a drug to make you sleepy. It will also help you stay pain free during the surgery. The staff will put an I.V. in your arm to give you fluids and drugs. When you are asleep, the doctors put a tube in your mouth to help you breathe.
- Your doctor will make small cuts in your rib area. Your doctor will put a scope with a small camera inside through one of the cuts. This will give images of the heart through a monitor inside the room.
- The doctor will put other surgical tools into the other holes to do the procedure.
- The doctor will make some small cuts in the upper part of the heart. This will make a maze-like pattern to guide the electrical signal to the wanted destination. In turn, these cuts will make scars. These scars do not have any electrical signals. They will stop other stray electrical signals.
- The doctor will close these cuts with stitches. In some cases, the doctor may use freezing or heating methods to make the scars.
- Your doctor will close the cuts in your ribs with stitches or staples and cover them with clean bandages.
