@zeke2u I have had two ablations. The stats say that 25% of all first ablations fail to close the access to the pulmonary veins of the atrial endothelium, which is how the spurious electrical signals get to the atrium and cause it to beat. I was in the unlucky 25%, but a second ablation seven months later has me free of AF for 33 months now. They work if the patient is a good candidate and if the electrophysiologist is highly skilled and highly experienced. New EPs won't have the experience to do a great job, unfortunately, so shop around far and wide, travel if you must.
