Intermountain Medical Center reseachers develop new 3-D technology to treat atrial fibrillation
Date:5/10/2013

SALT LAKE CITY Researchers at the Intermountain Heart Institute at Intermountain Medical Center have developed a new 3-D technology that for the first time allows cardiologists the ability to see the precise source of atrial fibrillation in the heart a breakthrough for a condition that affects nearly three million Americans.

This new technology that maps the electronic signals of the heart three dimensionally significantly improves the chances of successfully eliminating the heart rhythm disorder with a catheter ablation procedure, according to a new study presented at the Heart Rhythm Society's National Scientific Sessions in Denver on Saturday, May 11, 2013.

Atrial fibrillation occurs when electronic signals misfire in the heart, causing an irregular, and often chaotic, heartbeat in the upper left atrium of the heart.

Symptoms of atrial fibrillation include irregular or rapid heartbeat, palpitations, lightheadedness, extreme fatigue, shortness of breath or chest pain. However, not all people with atrial fibrillation experience symptoms.

"Historically, more advanced forms of atrial fibrillation were treated by arbitrarily creating scar tissue in the upper chambers of the heart in hopes of channeling these chaotic electrical signals that were causing atrial fibrillation," said researcher John Day, MD, director of the heart rhythm specialists at the Intermountain Heart Institute at Intermountain Medical Center. "The beauty of this new technology is that it allows us for the first time to actually see three dimensionally the source of these chaotic electrical signals in the heart causing atrial fibrillation."

Previously, cardiologists were able to map the heart in 3-D to enhance navigation of catheters, but this is the first time that they've utilized 3-D imaging technology to map the heart's specific electronic signals. Armed with this information, cardiologists can now pinpoint exactly where the misfiring signals are coming from and then "zap" or ablate that specific area in the heart and dramatically improve success rates.

With this new technology, cardiologists will now be able to treat thousands of more patients who suffer from advanced forms of atrial fibrillation and were previously not felt to be good candidates for this procedure.

"The capabilities of the new technology can be compared to a symphony concert," said Jared Bunch, MD, medical director for electrophysiology research at the Intermountain Heart Institute at Intermountain Medical Center. "During the concert, you have many different instruments all playing different parts, much like the heart has many frequencies that drive the heartbeat. This novel technology allows us to pinpoint the melody of an individual instrument, display it on a 3-D map and direct the ablation process."

The research team used the new 3-D mapping technology on 49 patients between 2012 and 2013 and compared them with nearly 200 patients with similar conditions who received conventional treatment during that same time period.

About one year after catheter ablation, nearly 79% of patients who had the 3-D procedure were free of their atrial fibrillation, compared to only 47.4% of patients who underwent a standard ablation procedure alone without the 3-D method.

"This new technology allows us to find the needles in the haystack, and as we ablate these areas we typically see termination or slowing of atrial fibrillation in our patients," says Dr. Day.

All of the patients in the study had failed medications and 37 percent had received prior catheter ablations. The average age of study participants was 65.5 years old and 94 percent had persistent/chronic atrial fibrillation.

Previous research has shown that the incidence of atrial fibrillation increases with age. A report from the American Heart Association shows the median age for patients with atrial fibrillation is 66.8 years for men and 74.6 years for women.

If untreated, atrial fibrillation can lead to blood clots, stroke and heart failure. In fact, people with atrial fibrillation are five times more likely to have a stroke than people without the condition.
