Not as bad as it sounds honestly and I really don't want to panic anyone but I just wanted to flag this up having recently seen my EP for my follow up appt 3 weeks after my ablation.
It's a bit of a long story but basically because of another issue ( liquid around my lungs) after my ablation I had a CT scan where very small PEs were found in the outer reaches of my lungs. I had been taking apixaban for 9 months before the procedure and also had a pre-ablation TOE which obviously was clear. On discovering the PEs the hospital swapped me into a clot busting dose of rivaroxaban and I will now remain on this drug for 6 months at least.
I only missed one dose of apixaban, as instructed, on the morning of the ablation but my EP is convinced that this could have been enough to cause a clot from my groin to travel into my lungs. He freely admitted that experience with NOACS is limited and that perhaps in hindsight I shouldn't have missed a dose.
I must stress that the PEs were by all accounts tiny, probably would never have caused me any issues and might never have been found unless I had had the scan. My EP told me that because no scans are routinely done after ablation it is possible that this happens to many people but is undetected.
Nonetheless I think it's worth mentioning and perhaps raising with your EP if you are on a NOAC and considering ablation especially if you have any other health issues - I am a reasonably young (50) and otherwise fit person with no history of any health issues so I was a little perturbed by all this!
