20. “I’m 80 and been in Chronic (persistent/permanent) A-Fib for 3 years. I actually feel somewhat better now than when I had occasional (Paroxysmal) A-Fib. Is it worth trying to get an ablation?”
With Chronic A-Fib of long duration, perhaps not. Although a few centers get very good results when treating Chronic A-Fib even of long duration (the French Bordeaux group achieves an acceptable success rate after 2 ablations), most centers have a success rate of only around 50% for Chronic A-Fib. And although catheter ablation is a low risk procedure, there are still risks.
Many centers won’t ablate patients who are over 80 years old or in Chronic A-Fib for over a year. There is a higher risk of complications in older people, and it is more difficult to ablate Chronic A-Fib. (In Chronic A-Fib there are often multiple spots in the heart producing A-Fib signals. It’s hard to identify and ablate [isolate] them all.)
The Positive Side of being in Chronic A-Fib: Sometimes people feel relieved to be in permanent A-Fib. There’s no longer the fear, uncertainty, and shock of an A-Fib attack. You can adjust your lifestyle to how your heart behaves, because it doesn’t change much. You may be short of breath, somewhat light headed, tired, and unable to work or exercise hard. But you get used to it. You may even feel better than when you had Paroxysmal A-Fib. In addition, an ablation may be only partially successful and have the unwanted consequence of putting you back into Paroxysmal A-Fib.
You still need to take blood thinners to prevent an A-Fib stroke. But if you get the Watchman or Lariat device installed (very low risk), it closes off your Left Atrial Appendage where 95% of A-Fib clots originate. It’s then possible to go off of Coumadin baring other risk factors for stroke.
The Negative Side of being in Chronic A-Fib: The down side of being in Chronic A-Fib is your heart forever and always will not pump properly. Blood flow to your brain and other organs is reduced by about 15%-30%. This can lead to conditions like dementia and Alzheimer’s. (If you are a superior athlete like a bicyclist or runner, your exercise may overcome this reduced blood flow.)
A-Fib is a progressive disease. It tends to get worse even in Chronic A-Fib. Your atria expand and stretch. Your ejection fraction diminishes. Chronic A-Fib produces fibrosis and collagen deposits which stiffen the heart and make it less flexible. All this leads to conditions such as Congestive Heart Failure and Cardiomyopathy
But please weigh the above statements carefully (the author is concerned that they may create unwarranted fear). How do you feel? If you don’t feel any symptoms and your doctor says your heart isn’t enlarging and/or developing poor ejection fraction, etc., then there’s no need to rush out to get a Pulmonary Vein Ablation which does involve real risk.
The Bottom Line: You can be cured of Chronic A-Fib, even at your age. But it will take at least 2 ablations. And it won’t be easy finding a doctor to do it. (There is a short list of doctors at Specialists In Persistent/Chronic A-Fib. You need someone with a proven track record in ablating Chronic A-Fib.) However, an ablation is more risky at your age.
On the other hand, you can live in Chronic A-Fib. Many people do. The key to living a satisfying life in Chronic A-Fib may be good rate control. For example, a resting heart rate of around 80 beats per minute with an exercise rate of 110 is very close to that of a normal person. People with good rate control of their Chronic A-Fib report a good quality of life and seem less prone to develop other heart or mental problems.
What this Means to You: Are you happy or content with your quality of life in Chronic A-Fib? If so, then the added hassles and risks of an ablation are probably not worth it for you. Only you (and your doctor) can decide if it’s better to spend your twilight years in a perhaps reduced but satisfactory quality of life.

19. “I have Chronic Atrial Fibrillation (the heart remains in A-Fib all the time). Am I a candidate for a Pulmonary Vein Ablation? Will it cure me? What are my chances of being cured compared to someone with Paroxysmal (occasional) A-Fib?”
This is a question that is currently in dispute among researchers in A-Fib. However, most clinical studies suggest that Paroxysmal is more frequently curable by PVA(PVI) than Chronic.
In fact, the French Bordeaux medical group, considered among the world’s leaders in A-Fib research, now uses a combination PVI and linear catheter ablation procedure for Chronic A-Fib as compared to a PVI ablation procedure for Paroxysmal A-Fib. They only consider patients with chronic A-Fib if they have “symptomatic and complicated AF” because of the following reasons: patients with Chronic A-Fib often have “poor hemodynamic tolerance” (their blood isn’t being pumped out properly), “suspicion of tachycardiomyopathy” (the heart tissue may have been damaged by the rapid, irregular heart beats or fibrillation), and “suspicion of thromboembolic events” (a greater risk of stroke).
Linear ablation techniques, though more difficult to perform effectively, may work better for people with chronic A-Fib and/or structural heart disease. In a Boston A-Fib Symposium 2006 presentation Dr. Jaïs from the French Bordeaux group reported a study in which 95% of Chronic A-Fib patients were restored to normal sinus rhythm.
For someone with Chronic A-Fib, you have a better chance of being cured of your A-Fib if you’ve been Chronic for a short period of time rather than for a number of years. Does that mean that people with Chronic A-Fib have little hope of being permanently cured by a catheter ablation? No. It’s just that right now most major heart centers have a long waiting list and have better success rates with Paroxysmal A-Fib.

Return to Frequently Asked Questions
By Steve S. Ryan, PhD, July 18, 2007, Updated October 2014
The French Bordeaux group uses a five-step process to treat Chronic A-Fib.
1. They start by isolating the Pulmonary Vein openings. They also eliminate potentials at the base of the Left Atrial Appendage, but do not isolate or electrically disconnect the whole of the LAA which could possibly lead to clots forming in the LAA and A-Fib stroke. (Ablating at the base of the LAA as part of the first step in treating A-Fib is a new approach and may become a very important first step in the ablation treatment of A-Fib.)
2. Next they make a roof line linear ablation linking the Right Superior Pulmonary Vein with the Left Superior Pulmonary vein opening to create complete electrical block
3. They then work in the Inferior Left Atrium and the Coronary Sinus. They make an incomplete blocking line between the Right Inferior and Left Inferior PVs in order to slow down the rapid atrial electrical activity.
They treat the Coronary Sinus as though it were another heart structure or Left Atrium, rather than just another vein opening. They disconnect the CS from the Left Atrium and ablate potentials along the Mitral Annulus. They also slow down Coronary Sinus electrical activity by ablating both inside and outside the CS with a lower wattage power, usually 25 Watts.
Editor’s comment: Treating the Coronary Sinus as another Left Atrium is a new approach. Most current A-Fib ablation procedures tend to stay away from the Coronary Sinus because of the risk of Stenosis (swelling). The French Bordeaux group, by using a low wattage, irrigated tip catheter, ablates within the Coronary Sinus without damaging it.
4. The fourth step is eliminating organized atrial activity in areas such as:
• Anterior Left Atrium & Left Atrial Appendage
• Posterior Left Atrium
• Superior Vena Cava
• Right Atrial Septum
5. The fifth step is to create a Mitral Isthmus blocking linear ablation line from the Mitral Annulus to the Left Inferior PV. The goal is to eliminate all potentials along this line.
In practice, even after these five steps, rapid atrial activity often remains. It has to be mapped, traced to its source and ablated. Often the top of the Left Atrial Appendage has to be ablated.
This whole procedure requires a great deal more time, effort, persistence, skill and experience than normal left ablation procedures.
