Maze Procedure -- Open Surgery

Maze is a surgical procedure for the heart. A maze-like pattern of incisions is made in the upper chambers of the heart. The chambers are called the atria.

  • Call Your Doctor

    • Redness, swelling, increasing pain, excessive bleeding, or discharge from the incision site
    • Nausea and/or vomiting that you cannot control with the medicines you were given after surgery, or which persist for more than two days after discharge from the hospital
    • Pain that you cannot control with the medicines you have been given

  • What to Expect

  • Reasons for Procedure


    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
    stroke
    .

    Maze is used to treat severe cases that did not respond to medicine or other procedures. Electrical impulses cannot flow through scar tissue. By creating specific patterns of scar tissue, maze surgery creates a pathway for healthy impulses and blocks erratic impulses.

  • Possible Complications


    Complications are rare, but no procedure is completely free of risk. If you are planning to have this procedure, your doctor will review a list of possible complications, which may include:

    • Infection
    • Bleeding
    • Anesthesia-related problems

    • The need for a permanent
      pacemaker
    • Kidney or other organ failure
    • Stroke
    • Death

    Before your procedure, talk to your doctor about ways to manage factors that may increase your risk of complications such as:

    • Smoking
    • Drinking
    • Chronic disease such as diabetes or obesity
    • The use of certain medications
