In a single word.....no. But.............it depends on several factors. It's not just your age, although by itself it should be no obstacle. Instead, what else is going on in you? Is your heart structurally sound? No valvular problems? No serious enlargement of the left atrium or the ventricle below it? No uncontrolled hypertension that would make those last two a high probability inside of a couple of years? Do you have other comorbidities that, taken together, make you a poor prospect for such a corrective operation, maybe even due to the need for general anesthetic?

Our organist at church learned he was in AFL at a doctor's visit. He had no idea. He and his wife are very active outdoors kayaking on the open ocean for fun. He was 77 at the time this happened. He needed two emergency ablations because the first didn't work. He's hale and hearty now, five years later, and every bit as active.

BTW, your first ablation was an astounding success. The EP should be on your Christmas mailing list, including a fine and expensive bottle of 20 year old Scotch. 😀 Many index ablations fail by about the 5th year. Getting 11 years, as you have, suggests that your EP knew what he/she was doing and did it perfectly. Alas, for almost all of us, time marches on and so does our cardiac electrical disorder. In time, most of us will need a 're-do' or a touchup to nip new pathways that once again have our hearts tripping over themselves.

One last point: there's no time like the present. You are, as you read this, in the very best condition you'll likely ever be in terms of the potential for success if you elect to undergo a second ablation. So get on this....yesterday.
