“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). (Added 2017: The Bordeaux group now uses ECGI (Medtronic’s CardioInsight system) in cases of Chronic A-Fib.)
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 FAQ Catheter Ablations
By Steve S. Ryan, PhD, September 2014
Medical breakthrough news! In a 10-year study that followed over 3,000 A-Fib patients who had a successful catheter ablation, researchers found a 60% reduction in the expected rate of cardiovascular mortality. This reduction of the risk of death from stroke and other cardiovascular events is phenomenal news!
Those of us who’ve had a catheter ablation (PVI) know how wonderful it is to have a heart that beats normally again. No other medical procedure produces such a dramatic and nearly immediate improvement in one’s quality of life. That a PVI also reduces the risk of death from stroke and other cardiovascular events is just ‘icing on the cake’. Dr Hamid Ghanbari, University of Michigan, author of the study says, “If successful, ablation improves life span.”
This research finding holds true not just for otherwise healthy A-Fib patients (i.e., Lone A-Fib), but also for A-Fib patients at higher health risk: older patients, those with diabetes, sleep apnea, low ejection fraction, and prior stroke and heart attack.
While successful ablation patients have the same mortality rate from ‘all causes’ (as those without A-Fib), being A-Fib free and back in sinus rhythm reduces cardiac mortality by 60%! This is great news for potential catheter ablation patients.
…a successful ablation… reduces cardiac mortality by 60%!
For anyone who has had a successful catheter ablation or who is thinking of having one, this study is a game changer!
We already know that a catheter ablation significantly improves quality of life. We certainly feel healthier in sinus rhythm. This study confirms the long-term benefits of catheter ablation even for people who are older and sicker.
We don’t have to live a life on meds! A-Fib can be cured by a catheter ablation. And when you are made A-Fib free, not only do you feel better, but you live longer! This is terrific news for the A-Fib community.
