I'm not telling my family (other than DH, of course) about this because I don't want them to worry yet...but I'm really worried. I'm 25 weeks pregnant today and had a perinatology growth scan because I have an abnormal cord insertion (velamentous). Baby looks fine in terms of growth and is measuring in the 76th percentile.
Now onto the scary part. A bit of background - at the anatomy scan with our first pregnancy in 2010, the perinatologists detected complex cardiac anomalies. They made it very clear at the time how serious they were. We had a series of follow-up visits with cardiac experts, all of whom told us that our baby would not survive long after birth, even with any amount of surgery, and we made the very difficult decision to end the pregnancy at 21 weeks rather than put the baby through any pain after birth. Since that time, we have had a healthy daughter with no known cardiac issues. With this pregnancy, the baby's heart looked normal at our anatomy scan at 18 weeks, and also looked normal at our fetal echocardiogram at the children's hospital at 20 weeks.
So at today's appointment, I noticed that the U/S tech was suddenly focusing a lot of attention on the baby's heart, and his demeanor changed a little bit. Given that I wasn't there to look at the heart, it was strange, so I asked him about it, and he said there was one thing that looked strange - the aortic artery is larger than the pulmonary artery, when it should be the other way around, or the same size. He brought in the perinatologist, who is a cardiac sonography expert (we know her from our first pregnancy). She had him test a whole bunch of other heart-related stuff, which all looked normal, but agreed that the aortic artery was larger than the pulmonary artery, and that was abnormal. She has the pediatric cardiologist who did our fetal echo at the children's hospital on speed dial, so she called her and asked her to get us in ASAP for a follow-up. She didn't want to provide any info on outcomes until we have more info.
According to Dr. Google, an aortic artery larger than a pulmonary artery is a strong indicator of congenital heart disease. It seems like it would strange to have this particular abnormality, however, without any other associated abnormalities. So we are crossing our fingers that it was just a strange view or something.
It's so strange that without the other reason for having an ultrasound today, I would be blissfully ignorant. At least if it is an indicator of a problem, we will know in advance and can deliver someplace where they can care for the baby's issues right away. Ugh, not what I was expecting as a result of today's appointment. Thanks for reading all of this!
