So I had the amniocentesis done today after the doctor gave us a 1 in 4 odds of down syndrome. He also did a detailed scan of the baby's heart and found that the baby has a significant heart defect that would require surgery at some point after birth. I believe it called it an atrialventricular defect? He encouraged us to follow through with the amnio because he said it is also commonly associated with downs or other chromosomal abnormalities and being aware of those (if they exist) would help us best prepare to treat baby. He is doing a rapid test, which he said would allow us answers from some of the more common chromosomal abnormalities by Friday (3 days from today) and a complete test that will take 7-10 days. He said that if the baby has a chromosomal abnormality that it lowers the prognosis of the surgery once the baby is born. I guess at this point I don't know what to think, what to do... My husband is unfortunately of no support at all. I'm hopeful and scared... especially when the doctor began talking about termination as an option if the results come back with an abnormality. I just never thought I would be experiencing this now, being 25, and fortunately having one healthy little boy already. Does anyone know what causes the heart defect? I've been there and got over the fact that if there is something chromosomal that I didn't cause it, but now I wonder about the baby's heart, if I did something to create that? I don't smoke, drink, or do drugs, never have. I'm relatively healthy, active... Any insight, personal experiences, or support would be greatly welcomed and appreciated.
