Open Chest Maze Procedure

WHAT YOU SHOULD KNOW:

Open chest maze procedure is heart surgery done to treat atrial fibrillation. Atrial fibrillation is an irregular and often rapid heartbeat. It is caused by fast random electrical messages to the heart muscle. The maze procedure makes a new heartbeat pathway that is shaped like a maze. The new pathway stops random messages and helps the heart to have a regular beat and normal rate. This procedure decreases your risk of stroke. The open chest maze procedure is usually done when other open heart surgery is needed.

INSTRUCTIONS:

Medicines:

  • Heart medicine: This medicine is given to strengthen or regulate your heartbeat.

  • Diuretics: This medicine is given to decrease edema (excess fluid) that collects in a part of your body, such as your legs. Diuretics can also remove excess fluid from around your heart or lungs and decrease your blood pressure. It is often called water pills. You may urinate more often when you take this medicine.

  • Blood pressure medicine: This is given to lower your blood pressure. A controlled blood pressure helps protect your organs, such as your heart, lungs, brain, and kidneys. Take your blood pressure medicine exactly as directed.

  • Warfarin: This medicine helps prevent clots from forming in the blood. Clots can cause strokes, heart attacks, and death. Warfarin may cause you to bleed or bruise more easily. Use a soft washcloth and an electric razor. Watch for blood in your urine and bowel movements. You may need to change your diet. Warfarin works best when you eat the same amount of vitamin K every day. Vitamin K is found in leafy green vegetables. Talk to your primary healthcare provider if you have questions or concerns about this medicine.

  • Take your medicine as directed: Contact your primary healthcare provider or cardiologist if you think your medicine is not helping or if you have side effects. Keep a list of the medicine, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits.

Heart rhythm checks:

You may need to be monitored for arrhythmias. This will let your cardiologist or primary healthcare provider know about problems with the rate or rhythm of your heartbeat. Ask your cardiologist or primary healthcare provider for more information about the following:

  • You may need to use a heart monitor at home. The monitoring may be done for a period of time such as a week or at regular times such as every month until your heart rhythm is regular. The device used to monitor your heart may be called an event monitor, Holter monitor, or mobile telemetry.

  • You may be taught how to check your pulse (heartbeat).

Daily weight:

Too much body fluid causes problems with your heart and lungs. Weight gain can be a sign of extra fluid in your body. Check your weight daily and write the results down. Keep track of how much your weight changes each day.

Reduce arrhythmia risk factors:

High blood pressure, sleep apnea (pauses in breathing while asleep), and obesity increase your risk of arrhythmias. Talk to your primary healthcare provider about ways to prevent or manage these risk factors.

Do not smoke:

If you smoke, it is never too late to quit. Ask for information about how to stop smoking if you need help.
