I'm TEE-boarded, but I personally don't like structural cases. They take too long and I start getting bored. I want to be doing open CV cases. However, I am good at structural, as evidenced by the fact that one of the interventional cardiologists specifically asks for anesthesia to perform the TEEs in his Amulet and Mitraclip procedures instead of the new "advanced cardiovascular imaging" cardiologist they recently hired.
Keep in mind this imaging doc is the same guy who asked the nurse to fetch his lead for him and for the "thing you hang the probe on" (ie. the christmas tree). Nurse had no idea what he was talking about. I just sat there and laughed. He also rolled into the room late one time and asked why I hadn't placed the TEE probe prior to the biplane moving in place. I told him that's not a service I offer.
