What to do...
Atrial fibrillation (AFib) is a type of irregular heartbeat that can cause several symptoms, such as chest pain and shortness of breath, and may lead to complications such as blood clots and stroke. There are several ways to treat AFib, including medications, cardioversion, and catheter ablation. However, for people who don’t respond to other treatments or can't tolerate them, the maze procedure is an option[1][2][3][4][5][6].
What is the Maze Procedure?
The maze procedure, also known as Cox-maze IV procedure, is a surgical treatment for AFib that creates a specific pattern of scar tissue in the upper chambers of the heart (atria) using a scalpel or a device that delivers heat or cold energy. The scar tissue blocks abnormal signals that cause atrial fibrillation, interfering with stray electrical heart signals that cause atrial fibrillation[2][3][6].
The maze procedure is successful in treating AFib in 60%–70% of patients, who can often stop taking blood thinners several months after the procedure[1]. It can also control heart rate, prevent blood clots, and reduce the risk of stroke[2][3].
Who Needs the Maze Procedure?
The maze procedure is used to treat people who don’t respond to other treatments or can't tolerate them. It's also a good option for people who need open-heart surgery for additional reasons (for example, to treat mitral valve disease) because both procedures can be performed at the same time[1][2][3][4][5][6].
Your healthcare provider might recommend the maze procedure if you have atrial fibrillation (AFib) that doesn't improve with medications or other procedures, or if AFib returns after treatment. If you're having another heart surgery, such as coronary artery bypass surgery or valve repair, the maze procedure might be done at the same time[3].
What Happens During the Maze Procedure?
The maze procedure can be performed in different ways, depending on the patient's condition and the surgeon's preference. The two most common types of maze surgery are:
- Open-heart maze procedure: If you need valve or bypass surgery for heart disease and you have AFib, your surgeon may do a maze procedure during your open-heart surgery. Your surgeon will break your breastbone, open your chest, and stop your heart to perform this surgery. The doctor will put you on a heart-lung machine to support you during this procedure[6].
- Minimally invasive maze surgery: Many people with AFib can have this type of surgery. It involves small cuts called keyholes so your surgeon can get to your heart. They will use energy, either heat or cold, to make scar tissue on your heart. This procedure can be performed while your heart is still beating[6].
Maze Procedure Recovery
After the maze procedure, you will need to stay in the hospital for a few days to recover. Your healthcare team will monitor your heart rhythm and vital signs. You may need to take medications to control your heart rate and prevent blood clots. You will also need to avoid strenuous activities and heavy lifting for several weeks after the procedure[1][2][3][4][5][6].
Other Medical and Surgical Treatments for AFib
In addition to the maze procedure, there are several other ways to treat atrial fibrillation, including:
- Medications: Several medications can help control heart rate and rhythm, and prevent blood clots. Your healthcare provider will determine the best medication for you based on your condition and medical history[1][2][3][4][5][6].
- Cardioversion: This is a procedure that uses electrical shocks to reset the heart to a normal rhythm. It can be done using paddles on the chest or through a catheter inserted into a vein[1][2][3][4][5][6].
- Catheter ablation: This is a minimally invasive procedure that destroys the tissue causing AFib. A catheter is inserted into a vein and guided to the heart, where it delivers energy to destroy the tissue. This procedure can be done while your heart is still beating[1][2][3][4][5][6].
Conclusion
Atrial fibrillation is a common heart condition that can cause several symptoms and complications. The maze procedure is a surgical treatment that creates a specific pattern of scar tissue in the upper chambers of the heart to block abnormal signals that cause atrial fibrillation. It is successful in treating AFib in 60%–70% of patients and can control heart rate, prevent blood clots, and reduce the risk of stroke. However, there are several other ways to treat atrial fibrillation, including medications, cardioversion, and catheter ablation. Your healthcare provider will determine the best treatment for you based on your condition and medical history.
