I recently read a couple of posts here on the afib forum in the states that said at 2 of the leading hospitals for cardiac care that as a matter of protocol 3 months after ablation the patient returns and has a cat scan of heart done to check for pulmonary vein stenosis that can happen up til 3 or 4 months after ablation without having any symptoms. Does this sound like a bit of overkill (pardon the expression). . I had my 1st ablation at a top hospital here and this was not ever mentioned to me. I would think one would have plenty of symptoms before ordering such a test. Any feedback on this? I have never read any such practice where you all are across the big pond.
