my fetal echo at 22 weeks missed them and only detected a possible VSD, well he had a huge
one and they told me the
day he was born right before my C/S. He was a sick baby and couldn't be on some of the heart meds they use for these issues normally so due to failure to grow and thrive at 10w old he had his open heart surgery.
As of a few weeks ago a follow up sedated echo (so he would be still) showed his heart %100 healthy!
