Thanks! I'll file that in my repertoire. I can understand the concern and the reason for the TEE prior to an ablation. It wasn't done in my case, or maybe it was part of the process while I was unconscious for my ablations. I was just told that it was to ensure the adjacent structure wasn't going to get burned along with the substrate they wanted to neutralize. But they might have inserted the TEE device immediately and taken a good look for clots, and THEN commenced the ablation. Makes sense.
