Arrhythmia Surgery in Hollywood

Arrhythmia Surgery Performed at the California Heart & Lung Surgery Center


The MAZE surgical treatment has proved to be very effective for curing arrhythmia, regardless of the severity of the condition. Nevertheless, before undergoing this intervention in one of our LA locations, Dr. Alexander Marmureanu will ask you to go through a series of tests and examination procedures in order to thoroughly assess your condition and overall health. Some of the following tests will thus be required prior to the MAZE surgery:

  • Blood tests
  • Electrocardiogram (EKG)
  • Holter and Event Monitor: A device will record the activity of your heart for 24-48 hours.
  • Stress test
  • Chest X-rays
  • Echocardiography
  • Coronary angiography
  • Electrophysiology study

The date of the procedure will be set after you have been deemed eligible for MAZE surgery. On the day of the surgery, you will first be put under general anesthesia by the team at the California Heart & Lung Surgery Center, irrespective of the treatment approach used (open-heart or minimally invasive). An incision or, if you undergo minimally invasive surgery, several small cuts will be made in your chest bone to allow us access to your heart. The tissue of your atria will be subsequently scarred in multiple places using one of the following techniques, depending on the particularities of your condition:

  • radio waves
  • ultrasound energy
  • small incisions
  • microwave energy

Scar tissue is unable to conduct electrical activity in your heart. Consequently, the electrical signals will go through a path (or maze, hence the name of this procedure) of scar tissue towards the ventricles (the lower chambers of the heart) following surgery, which will regulate the electrical activity of your heart, eliminating thus the cause of the arrhythmia. After the intervention is completed, your incision will be closed with stitches and a sterile dressing will cover your wound to avoid infection until it heals.

Who Needs Arrhythmia Surgery


The MAZE surgical treatment approach is preponderantly employed for patients suffering from severe atrial fibrillation, a condition which often requires surgery to prevent serious complications such as strokes and improve the quality of life.

Patients in the following categories may be the perfect candidates for MAZE surgery:

  • the symptoms of their atrial fibrillation cannot be alleviated by medication
  • the atrial fibrillation is particularly severe, entailing a high risk of complications
  • patients who cannot take anticoagulant medication, commonly prescribed for atrial fibrillation in order to avoid strokes, due to various health conditions

What to Expect After Arrhythmia Surgery


Once your arrhythmia surgery is completed, you will be moved to the intensive care unit, where medical professionals will permanently monitor your vital signs for 2 or 3 days. You will generally need to spend 7 to 10 days hospitalized until you partially recover. Shortly after the effects of anesthesia wear off, you will begin to feel pain and discomfort in your chest, ribs, and shoulders, which is completely normal within the first week. In order to alleviate your symptoms and avoid postoperative complications, you will be administered the following medication during your hospital stay:

  • pain relievers
  • antibiotics, to prevent infection, which you start receiving during your surgery
  • anticoagulants (blood thinners) such as warfarin, to prevent the forming of blood clots
  • diuretics, to control the amount of fluid which will accumulate within your chest cavity for several days after the intervention

You will also be intubated for the first few days. Multiple tubes will be attached to various regions of your body, such as:

  • drainage tubes inserted through your incision to remove excessive fluid from your chest cavity
  • a urinary catheter attached to your bladder to collect urine until you are able to use the restroom on your own
  • an IV line in your arm, which will supply your bloodstream with medication and fluids

Complete recovery is typically achieved in 2 months. However, after your discharge from the hospital, you will be highly encouraged to take into consideration the following recommendations, so that you will experience a faster recovery and maintain the health of your heart:

  • quit or at least reduce the frequency of smoking to promote proper functioning of your heart and lungs
  • monitor your food intake, as well as the type of food you consume – it is recommended to opt for products which are low in saturated fat, cholesterol, salt and sugar, and to include a lot of whole grains, fruits, and vegetables in your diet
  • take your medication for as long as your physician advised you to achieve thorough recovery and avoid complications
  • engage in sports or exercise regularly – however, you should ask your physician what activities you are allowed to perform after the surgery
