Hi, Dejaboo, I'm so sorry to hear you had a bad experience with the TEE test. I think for most of us the TEE was quite uneventful. It does sound as if you were not sedated enough. When I had mine done I did not fall asleep but felt quite drowsy; I did not feel a thing. Did they also spray your throat to numb it?
With regards to the neurologist, you may not need one if you no longer have neurological symptoms (I know you mentioned you had a TIA at one point). However, your doctor MAY need a supporting second opinion before going ahead with the procedure. I say MAY because it might depend on the facility where the procedure will be performed, the doctor, etc. I'm not sure what the current protocol is since this is emerging science (PFO closure through catherer) so it seems to change frequently. Each facility, doctor, state, etc. may have its way of doing things. Check with your cardio to see if he needs the supporting opinion of the neuro before going ahead with the procedure.
I hope all goes well for you. You have been through a lot already and it would be easier on your body if they could perform the less invasive procedure with catherer closure. You sound like you have a good cardio who will take great care of you! We are all sending lots of positive thoughts your way.
