early fetal cardiac ecoFrom: Wolfgang Moroder, M.D. (wolfgang.moroder@tin.it)Wed Oct 20 01:58:41 2004
Dear Terry I have tried to send you an e-mail but it seems that the anti spam devices don't allow it to go through. I'd like to post as an informal case three videoclips for a total of about 5 MB. The first color Doppler videclip shows the fetal heart at 12 weeks and that looks normal as far as it can be investigated at this stage. The second and third clips are of a chromosomically normal fetus at 14 and 16 weeks. There is clear evidence already at 14 weeks of an unbalanced AV canal with a single common atrioventricular valve orifice. The first frames of the clip show a fairly normal three vessel view. There seems to be an evolution towards a more severely disproportion between the two ventricles and a single ventricle heart looking at the 16 weeks clip. The unbalanced form of AV canal is more common in chromosomically normal fetuses. The pregnancy is still ongoing and the patient is waiting for a more conclusive scan and councelling at 20 weeks. For better viewing of the clips I suggest to load them from Quicktime. To my knowledge Quicktime compared to Mediaplayer has the advantage to allow a frame to frame vision of the videoclips using the right and left arrow on the computer's keeboard. The spacebar can be used as a stop and play command while control-L is a shortcut to make the clip loop. Analising color Doppler videoclips by a frame to frame method is almost essential because shifts in colors are very quick and can't be observed easyly even by a trained eye. If you consider this material interesting for publishing as a informal case I'd be very happy to send it. Please let me know how I can upload it to the OBGYN.NET server. Best regards Wolfgang

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
