Our Program

The USC Center for the Comprehensive Treatment of Atrial Fibrillation at Keck Medicine of USC is comprised of a team of specialists whose diagnostic and treatment skills are focused on patients with atrial fibrillation. Atrial fibrillation, AF or A-fib, is the most common type of cardiac arrhythmia (abnormal heart rhythm). It involves the two upper chambers (atria) of the heart. Its name comes from the fibrillating, or quivering, of the heart muscles of the atria, instead of the standard, coordinated contraction typically found in healthy hearts. Nearly two million people in the United States are currently living with this condition. However, those who walk through our doors are treated uniquely and as individuals.

Our services include:

  • 3D mapping and intracardiac ultrasound to guide catheter treatments
  • Minimally invasive surgery techniques
  • Combined endocardial and epicardial approaches
  • Medication treatments
  • Wireless arrhythmia monitoring to aid treatment decisions

Maze procedures are highly effective in patients with atrial fibrillation and are often conducted concomitantly with other procedures. These include mitral valve repair (MVRpr), coronary bypass graft (CABG), aortic valve replacement (AVR), mitral valve replacement (MVR), tricuspid valve repair and replacement (TVR), epicardial pacer leads, atrial septal defect closure (ASD), carotid, replacement removal, aortic aneurysm, myotomy/myectomy, patent foramen ovale closure (PFO) and right ventricular assist device (RVAD).

Maze Procedure
The Maze Procedure is surgery performed to treat atrial fibrillation. During the procedure, a number of incisions are made on the left and right atria to form scar tissue, which does not conduct electricity and disrupts the path of abnormal electrical impulses. The scar tissue also prevents erratic electrical signals from recurring. After the incisions are made, the atrium is sewn together to allow it to hold blood and contract to push blood into the ventricle.

Open Chest Maze Surgery
Open chest Maze surgery means that the sternum is divided to allow access to the chest. During this surgery, the heart is stopped and a heart-lung machine is used. Scissors are used to open the pericardium to gain access to the heart.

Minimally Invasive Maze Surgery
Minimally invasive maze surgery is performed through small keyhole incisions made between the ribs, through which a tiny camera and video-guided instruments are inserted. When appropriate, robots are used to assist the surgeon during the procedure.

This minimally invasive surgery eliminates the need for dividing the breastbone (sternum), does not require the heart to be stopped and does not require a heart-lung machine to be used. This often results in less pain, shorter recovery times and a lower risk of infection associated with open-heart surgery.

Our Approach

At the USC Center for the Comprehensive Treatment of Atrial Fibrillation, we focus on the diagnosis and treatment of abnormal heart rhythms of which there are many different types. We offer full diagnostic services and a vast array of treatment options.

The center’s affiliation with the USC CardioVascular Thoracic Institute allows close, comprehensive communication among nurse specialists, cardiologists, cardiac electrophysiologists, cardiac surgeons and others specializing in this field. This unique approach enables us to adopt and provide the most advanced diagnostic and therapeutic technologies. The center frequently acquires access to new technology and therapies before they enter mainstream medicine.
