Catheter ablation

Hi I am a 68 year old male who had a double bypass 5 years previously. I was diagnosed with atrial flutter some 14 months ago, and had a catheter ablation to cure this. However, I came out with LBBB & bradycardia. Is it possible that the electrophysiologist made an error & inadvertantly ablated the pathway, which led to the LBBB? Thanks Paul

It's definitely possible to ablate the wrong pathway.  I am not sure why he though, given that atrial flutters come from atria and the Left Bundle resides in the left ventricle.  He would have had to go into the left ventricle to ablate an atrial flutter which doesn't make any sense to me.  We do this quite a bit here and this has never happened.  It is more likely that the left bundle block is unrelated to the procedure.  I hope this helps.
