If it helps, first ablations have a 30-40% failure rate, depending on the skills and experience of the EP. Subsequent ablations run around 80% success rate. But, again, the performing 'artist' determines those numbers, not so much the patient. I can't stress enough that you must find and secure the help of the top 15 EPs in the country if at all possible.

Again, if it helps, I am one of those unfortunate statistics, and I'm still haunting the www posting encouragement, coaching, and advice to those who seem to need it. In fact, I have been in the ER five times since my July ablation, all due to flutter or AF. My EP accepted the graphic depiction of my HR from my Galaxy watch as evidence that his first work hadn't worked, and he called to chat and to say he'd be willing to try again. Happily, on February 14th, he went in and found that he had to re-do the isolation of three of the four pulmonary vein ostia (mouths, where they empty oxygenated blood returning from the lungs to the left atrium).
Not only that, but as soon as he burnt the last gap, my heart immediately resumed Normal Sinus Rhythm (NSR), at which he and his team stood back and high-fived. He told me he didn't even have to shock me back into rhythm, which is almost always the last necessary step for a heart as disordered as mine is/was.
Ablation isn't kids' stuff, but it's more-and-more routine and necessary for the heavy majority of AF sufferers. It may only buy you several years until the problem returns, but then you go and have a touch-up again, which is really all a second or third ablation is. And, one last time, the person moderating afibbers.org forums has had seven ablations. One poor woman who posts there daily has had over 50 cardioversions, and finally had to settle on a pacemaker to keep her alive. That's another story and best left to another conversation. The point is, you have options, none are what could charitably be called lethal or dangerous, and they offer a much better quality of life when all is said and done.
Don't shy away from skilled help, and don't be afraid of ablation. It's not open heart surgery after all.
