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
