Just had my 20 week ultrasound and they found one soft marker for down syndrome. It is a bright spot that was found on the heart. I did not have the NT scan done and I am 37 yr old. Needless to say we are worried. I know I can have an amino done but concerned about the risks. I will talk to my OB about this at my next appointment, but does anyone have a similar experience? Trying not to flip out too much.

Echogenic intercardiac focii.
They found one on the ultrasound for my daughter as well. It is a VERY soft marker, representing possibly a doubling of your chances of having chromosomal abnormalities. Be aware that the likelihood of these is already low, as in my case where 'doubling' my chances (at age 40) meant we went up to having a 1.4% chance. Even without an NT scan there are other factors they can look at non invasively, nose bone length, development of leg bones, etc. etc. Talk to your OB and I am sure that they will reassure you and give you numbers on what your chances are that should be very good.
By the time it was seen on the ultrasound, we were already in week 28, but my husband and I decided to get an amnio done anyway, just so that we could be prepared in case there were issues. As it turned out, everything was normal, no chromosomal issues and in fact, by the time I had my last ultrasound the 'star' was gone from her heart.
