Maze is done to treat
atrial fibrillation. Fibrillation is abnormal beating of the heart muscle. It is caused by erratic electrical impulses that travel through the heart muscle. These impulses can cause the chambers to beat too fast. This can decrease blood flow through the heart. Atrial fibrillation can also cause blood clots to form in the heart that can travel to the brain and cause a
Maze is used to treat severe cases that did not respond to medications or other procedures. Electrical impulses cannot flow through scar tissue. By creating specific patterns of scar tissue, the surgery creates a pathway for healthy impulses and blocks erratic impulses. The scars may look like a maze.
After you are asleep, the doctor will cut through the skin and breastbone. The chest cavity will be opened. Next, the heart will be connected to the heart-lung machine. This machine will take over the functions of the heart and lungs during surgery. Once the machine is active, the heart will be stopped.
A series of small cuts will be made in the atria. The cuts will be made in a pattern to direct the electrical impulses that may look like a maze. The incisions will then be closed with sutures. In some cases, a pacemaker may need to be placed.
Once the maze-like pattern has been completed, the heart will be restarted. When the heart is working well, you will be removed from the heart-lung machine. The chest will be closed with wires. Finally, the skin will be closed with sutures.
