Patient discussion about trans acting.

Q. My mother had a chest pain and she was sent for a TEE. When do you need a TEE and when a normal echo is fine? My mother had a chest pain few weeks ago. we were sure its a heart attack and went to the ER. There the doctors did some tests and she was sent for a (trans thoracic echocardiogram) TEE. I want to know when do you need a TEE and when you can do just a normal echocardiogram because the TEE was very painful for her and we want to know if ther was a better way.

A. The main difference between TEE and normal echo is that in TEE u put the transducer directly in the esophagus. The transducer is the same and the idea is to put it as close as possible to the heart.
As far as I know there are some heart situations the TEE is better for diagnosis that normal echo. Maybe your mom had one of those situations?
I can recommend you to ask the ER doctor. he will probably be able to give a better explanation for his choice
