| Transesophageal Echocardiogram What is a Transesophageal Echocardiogram? A transesophageal echocardiogram is a special
ultrasound test that uses sound waves to take
pictures of the heart. This type of echo
can take clearer pictures of the heart
than regular ultrasound especially in older children
and adults. It is also used during heart
operations to help guide the surgeon. There is
no known risk from ultrasound exposure
and no radiation exposure is involved. How is it done? The study is done by passing a special
tube down the throat
into the esophagus or food pipe.
The end of this tube is placed
near the heart which allows
very clear, detailed pictures to be taken. So, can you think of any reason this procedure might
lead to swallowing dysfunction?

off the top of my head im thinking that the tube entering the part of the airway and into the esophagus may cause acute irritation/damage to the tissue. this could result in edema which would affect swallow function. i will think about it a little more and get back to you. there are a few things i want to get back to you on this weekend. we'll just add this one to the list : ) i also want to comment on the article you gave me to read. and then get the next one. good stuff!
Christie,
I realize you are a full-time student so I did a little research for you...
There could also be damage to RLN of Vagus, which could lead to paralyzed vocal folds, temporary or permanent, which would lead to swallow dysfunction. I'll write more as I think of them.
