“I’m getting by with my Atrial Fibrillation. With the recent improvements in Pulmonary Vein ablation techniques, should I wait until a better technique is developed?”
A-Fib is a progressive disease. The longer you have it, in general the worse it gets. In a process called “remodeling” your heart may change physically and electrically if you have A-Fib long enough. The longer you have A-Fib, the harder it is to cure.
For instance, a patient can be diagnosed with paroxysmal A-Fib initially and then transition to persistent, and eventually to long-standing persistent A-Fib. This progressive nature of atrial fibrillation is why doctors say, “A-Fib begets A-Fib”.
So, it’s important to be cured as soon as reasonably possible. See our Overview of A-Fib.
With today’s current Pulmonary Vein Ablation (Isolation) procedures using Pulmonary Vein Potentials, you have an 70%-85% chance of becoming A-Fib-free (in cases of Paroxysmal A-Fib). (The other 15% though not cured are often significantly improved; meds that didn’t work before may now work.) With a second ablation the success rate is 90% or greater.
So don’t wait. Your odds aren’t going to get much better than that.

“How long do I have before my A-Fib goes into chronic or permanent A-Fib? I know it’s harder to cure. I’ve had Paroxysmal (occasional) A-Fib for a couple of months, but the A-Fib episodes seem to be getting longer and more frequent.
Worst case scenario, Paroxysmal (occasional) A-Fib can progress to permanent in about one year. In a study of 5,000+ A-Fib patients, 54% of those on rate control meds went into permanent A-Fib in one year. However, there are people who’ve had Paroxysmal A-Fib for years and never progress to permanent A-Fib.
But the odds are against you. You are correct that the longer you have Atrial Fibrillation, the harder it can be to cure it. Consider working aggressively to stop your A-Fib as with antiarrhythmic meds or with a minimally-invasive Pulmonary Vein Ablation or a Mini-maze surgery. You don’t want to be part of the 54% whose A-Fib becomes permanent.1
To learn about various Treatment options for Atrial Fibrillation, see our Treatments page. Think about your treatment goals. Is managing your A-Fib and increased stroke risk with meds okay with you? Or do you prefer to aim for a cure? Discuss the options with your doctor. Take action as soon as practical.
