Victoria Farraj was with her kindergarten class, dealing with an 鈥渆xceptionally active鈥� student, the first time it happened. Her heart suddenly started racing.
By the time Victoria, then 61 years old, got home that day in January 2013, the problem went away. But about one year later, Victoria鈥檚 heart began to beat so fast she felt as if it could leap out of her chest.
An electrocardiogram at her doctor鈥檚 office told the story: It was atrial fibrillation (AFib), the most common type of heart arrhythmia, where the heart beats in an irregular manner.
Most likely to strike after age 60, AFib can occur at any age. Left untreated, it can lead to heart failure symptoms, stroke and other complications.
Under a cardiologist鈥檚 care, Victoria began taking medications to control her rapid heartbeat.
But her heart would still periodically start racing at 132 to 138 beats per minute, often waking her in the night. A normal resting heart rate is 60 to 100 beats per minute.
鈥淚t鈥檚 so disconcerting to have AFib because it just happens,鈥� says Victoria, noting that the physically draining episodes kept her from exercising and traveling. 鈥淭here鈥檚 no warning.鈥�
Other interventions followed. Over a nearly two-year period, Victoria had a cardioversion procedure 鈥� quick, low-energy shocks to the heart to restore a regular rhythm 鈥� three times.
She also had two cardiac ablations that involved the threading of a thin, flexible tube called a catheter through her veins into her heart to create scar tissue to break up the irregular rhythm.
Victoria鈥檚 doctors determined she had a type of AFib called long-standing persistent atrial fibrillation.
“It’s difficult to treat, and a very different disease than paroxysmal (occasional) AFib,” says Jonathan Praeger, MD, a cardiothoracic surgeon at the 喵咪社区 Cardiac and Vascular Institute.
Victoria was referred to Dr. Praeger in the fall of 2021 to learn about an AFib treatment option she had never heard of 鈥� the totally thoracoscopic maze (TT Maze) 鈥� that might finally bring relief.
In a maze procedure, a surgeon uses different types of energy to create scar tissue in a pattern (maze) on the heart鈥檚 upper chambers because scar tissue can鈥檛 conduct electricity.
As a result, the 鈥渕aze鈥� blocks the faulty electrical signals behind AFib while allowing normal heartbeat signals to get through.
A standard maze involves open-heart surgery and is usually performed on patients who have other cardiac issues, such as coronary artery disease. The minimally invasive TT Maze approach is done for individuals dealing only with AFib.
鈥淚 work through incisions a centimeter wide,鈥� Dr. Praeger says. 鈥淵ou get close to all the benefits of a traditional maze procedure without having to open the chest.鈥�

It’s so disconcerting to have AFib because it just happens. There’s no warning.
Victoria underwent a TT Maze procedure in February.
After making a few small incisions, Dr. Praeger deployed an endoscope 鈥� a thin tube with a video camera at one end 鈥� to view magnified images of Victoria鈥檚 heart in real time.
Using radiofrequency, he built a scar pattern on the exterior of her heart鈥檚 left upper chamber. He then clipped and excluded the left atrial appendage, a blind pouch where the blood pools and clots typically form.
Finally, Dr. Praeger removed a piece of unneeded tissue on the outside of the heart, called the ligament of Marshall, which can be a source of AFib.
Before Victoria left the operating room, her heart had returned to normal sinus rhythm.
鈥淎lmost always, I can watch a patient鈥檚 heart convert back to a healthy rhythm as soon as the procedure is over,鈥� Dr. Praeger says. 鈥淚t鈥檚 so gratifying to watch the hemodynamics improve.鈥�
The heart takes about three months to settle into its new rhythm. Victoria experienced a few minor incidents of AFib soon after the procedure, but she has been in good health since.
鈥淚 feel wonderful,鈥� says Victoria, who is now 72 and living in Glendora.
Under her cardiologist鈥檚 direction, Victoria began weaning off her heart medications. She is back to taking long walks, helping to care for her young grandson, Archer, and enjoying life with her husband, George.
The TT Maze procedure 鈥� which offers a quicker recovery and less bleeding and postoperative pain than a standard open-heart maze 鈥� is technically challenging to perform and not widely available.
鈥淭he fact that we can offer it here at Keck Medicine speaks to our expertise and our willingness to take on innovative procedures,鈥� Dr. Praeger says. 鈥淚t has changed patients鈥� lives, and that success is what drives me to continue.鈥�
