Surgical Treatment for Atrial Fibrillation
WebMD Live Events Transcript
Atrial fibrillation (AF) is
the most common form of irregular heartbeat and affects about 2.2 million
Americans. People with atrial fibrillation are at increased risk for
life-threatening strokes. In addition, AF can damage the heart and lead to heart
attack and heart failure. Cleveland Clinic heart surgeon A. Marc Gillinov, MD,
joined us on Feb. 1, 2005 to discuss the latest surgical techniques for treating
AF and restoring normal cardiac rhythm.

Welcome to WebMD
Live Dr. Gillinov. Please begin by telling us about the Cleveland Clinic Heart
The Cleveland Clinic is the largest cardiac surgery and cardiology surgery program in North America. We treat all forms of cardiovascular disease and have particular expertise in the treatments of atrial fibrillation (AF) and heart valve disease.
I have had persistent atrial fibrillation for one year, no other health problems and I am 81 years old. I do not like the effects of the medications. Does my age present a barrier to having the procedure (ablation, minimally invasive)?
Ablation is occasionally indicated in people over the age of 80. Such an individual should consider ablation only if the atrial fibrillation is very symptomatic or the patient has suffered a stroke from the atrial fibrillation.
|"The natural history of untreated atrial fibrillation is that it becomes more frequent until it is present all the time."|
What are the risks of ablation, and rates of occurrence?
Ablation is a general term used to describe a procedure to cure atrial fibrillation. The procedure may be performed with minimally invasive surgery or in some cases, with a catheter. The ablation procedure creates areas of conduction block in the heart. The success rate in people with intermittent atrial fibrillation is about 80%. The success rate for people who are in continuous atrial fibrillation is about 70%.
I am a 45-year-old male with occasional atrial fibrillation. I have had it for about 10 years. If it is occasional do I need to get it fixed surgically? I take no medicines for it.
If the atrial fibrillation only occurs occasionally and does not cause severe symptoms and has not caused a stroke, then it does not require an intervention like ablation. However, it would generally be wise to take aspirin in this instance.
Does atrial fibrillation get worse over time?
Yes. The natural history of untreated atrial fibrillation is that it becomes more frequent until it is present all the time. Atrial fibrillation decreases heart function and it is associated with a risk of stroke. The longer a person is in atrial fibrillation the greater the cumulative risks of decreased heart function and stroke.
