I also have afib and flutter and am on Sotalol and a small dose of carvedilol and valsartan. I've had a few ablations as well and it keeps returning. My heart wants to beat too fast so the last resort will be a pacemaker that will be 100% responsible for my heartbeat, which I want to avoid. Last December (2023), my doctor performed a "regular" ablation and also a "Vein of Marshall with alcohol infusion ablation" and it has worked thus far. I'd not heard of the vein of marshall... before but it's a vein in the back of the heart, not in the same place for everyone and can be difficult to reach, and in a very few small percentage of patients it can't be reached. If you've not heard of that one before it might be something to ask your doctor about. There are YouTube videos that explain if you're interested.
I wish everyone good health.
