I had an ablation for SVT done 8 months ago. I went into cardiac tamponade about an hour after the surgery, while in the recovery room. I had felt fine until I didn't. ICU for 4 days. Emergency Chest drain and then sent home. Kept getting worse and was told "everyone recovers differently." I have taught exercise for 45 years. Excellent conditioning and I know my body and when something is off. My EP, who is the head of the EP program and only does this type of surgery day in a day out for the last 15 years, told me I was her healthiest patient (I joked with her to not jinx the surgery....) hindsight. Finally diagnosed with Post Cardiac Injury Syndrome almost a month after the ablation - a type of pericarditis - I had pleural effusions that had to be drained and I was hospitalized once more because of the pleural effusions. Had to go on prednisone, naproxen and colchicine. STILL on the meds although I am slowly tapering off prednisone. If I'd had a crystal ball - well I don't know what I would have done. It has been a blessing NOT to have SVT since February (I was having multiple episodes daily). And my EP is very confident, because of the type of SVT it was, that I will be free from this. Having said this - if it every comes back - fingers crossed it won't - I will pick medication over another ablation - but then I have to with how my body reacted to the first surgery (and only surgery that I've had in my life). Even my EP said I would not be a candidate for another ablation because my body reacted with systemic inflammation that will probably take a year or more to get over. And then monitor for an additional 3+ years. I am back to teaching class (yoga for now) and I am walking and on my treadmill. But I am not back to pre-ablation exercise levels, walking up hills can be challenging some days and a breeze the next. Additionally, I remember the EP introducing me to a cardiology fellow and saying he would assist her if that was ok - I didn't know what a fellow was in terms of the medical field - but it's people learning how to do what she does. If I'd known that I would have said no. I believe this is why this happened to me. My EP was devastated and said this has never happened in her entire career and she has never treated someone with this. In fact I am a case study at the hospital now because they've only read about this in their medical school classes.
