Atrial Fibrillation (AF or A-fib)

Louisville’s foremost source of atrial fibrillation care

Norton Heart & Vascular Institute’s specialists are the leading providers of atrial fibrillation (A-fib) care in Louisville and Southern Indiana. They treat more than 400 atrial fibrillation patients a year.

Norton Hospital and Norton Audubon Hospital have the highest level certification status from the American College of Cardiology to treat this most common of the heart arrhythmias.

Through the Norton Heart & Vascular Institute Heart Rhythm Center, our four board-certified and fellowship-trained electrophysiologists have the technology to pinpoint the cause of your A-fib.

With a clear understanding of your A-fib causes, our specialists will work closely with you to customize a treatment plan that can get you back to living your life.

Our specialists have the skill and experience to know whether your A-fib can be controlled with medication or require more sophisticated treatment, such as ablation or other surgical options.

Personalized A-fib treatment

Atrial fibrillation causes the upper chambers of the heart to beat quickly and irregularly. A-fib puts those who suffer from it at five times the usual risk for stroke and can lead to heart failure.

Many people don’t know they have it.

The Norton Heart & Vascular Institute atrial fibrillation teams handle diagnosis and develop a treatment plan that is right for you. Our experts also are ready to evaluate more advanced cases that may require minimally invasive surgery that typically doesn’t require a night in the hospital.

Our providers have expertise in a common treatment for A-fib — catheter ablation. In this procedure, the surgeon threads a tool through a vein guided by a 3-D map of your heart. At the spot of tissue that’s causing the irregular heartbeat, the surgeon delivers a small burst of heat, radio frequency or cryoablation (cold) — depending on your condition — to destroy the malfunctioning tissue causing A-fib.

To reduce the risk of an A-fib-related stroke, Norton Heart & Vascular Institute has been performing Watchman implants longer than any other hospital system in Louisville or Southern Indiana. The implant, first used in Louisville in 2016 at the Norton Heart & Vascular Institute, prevents blood clots from breaking loose in the left atrial appendage and entering the bloodstream. The implant allows many patients to stop taking blood-thinning medication, such as warfarin, and is a treatment for those that are unable to take blood thinners.

Our care for your heart doesn’t stop when you go home. We provide 24-hour Holter monitors, 30-day event recorders, complete follow-up care and wireless device monitoring for Louisville-area patients with pacemakers and implantable defibrillators.
