| Hello, |
Thank you for your query at DoctorSpring.com
I have gone through your case history. The recurrence of atrial fibrillation is usually due to re growth of sleeve across the ablation site. Usually we say ablation is successful if there is no recurrence of fibrillation even after one year of procedure.
In your case since you have recurrence of Atrial fibrillation though not sustained you should be require repeat electrophysiological study to confirm the growth of sleeves across the ablation site.
Patient replied :
Thank you doctor. Yes I never had a complete remission from AF. I even had it after the operation and it has continued although non sustained.
Is my initial my initial statement plausible? Ie that although I can get AF for 10-30 seconds the fact that my pulmonary veins are abated (as mentioned the 2nd ablation confirmed they were still isolated) and the scarring from my 2nd ablation is enough to mean the arrythmia (so far at least) cannot be sustained?
Since you didn't have complete relief from A Fib from the first procedure , so it's possible that during the first procedure the whole trans-mural myocardium that is whole thickness of the muscle may not have been ablated and some fibers would have escaped and would have regrown now to develop A Fib rather than the scar of second ablation
