It is very likely that a clear image can be gained without swallowing the
probe. It is certainly worth the try first. I was told the same thing and
yet the external view proved to be clear and the correct angle. The same was
found in most of the agitated saline solution examines that I am aware of in
our group.
I suspect that physical composition may determine the need to swallow.
Something like that anyway,
RMC

Subject: PFO evaluation
Re: Andrew�s post:
An invasive cardiologist at the University of FL School of Medicine
confirmed Andrew�s doctor�s opinion on PFO evaluation (this was a few months
ago when the debate surfaced on the tech list). Conventional ultrasonography
alone probably will not reveal a PFO, which occurs in 25-30% of the
population. To reliably demonstrate a patent foramen, the technician would
inject agitated saline and follow with a trans-esophageal lead (this
involves swallowing a tube with an ultrasound lead implanted---somewhat
invasive).
His comment to me was, �if you have a PFO, does this mean you�ll give up
diving? Cave diving? Decompression dives?�
That�s what the doc said�
Best,
Barbara/San Francisco
