20 week scan - baby heart issue PLSVC :(

[Babysmith0506]

We had our 20 week scan yesterday and unfortunately they found a Persistent left superior vena cava heart issue

PLSVC as it is known apparently all babies have 4 blood vessels stemming from the heart until 8 weeks gestation and then one recedes and you’re left with 3. Unfortunately our baby still has 4 vessels at 20 weeks, so we need to see a detail cardiologist. They said the other aspects of the heart look normal and they are hoping this is just an asymptomatic anomaly. But we won’t know that until we have a more detailed echo scan I assume.

We are so so so worried and it was a big shock, apparently this only happens in 0.3% of people so it’s really rare. Has anyone experienced this with their babies or kids?

@Eirth25 Yes my birth plan should be able to stay the same. Only difference right now is the extra check up once she is born, but I feel relieved to know that she won’t need to go straight away. I was wondering if I would need an extended stay in hospital for the extra checks but at least now I know and I can start to think about packing my hospital bag!

Just reporting back for anyone that might find it useful. Same here at 28 week scan. Fetal cardiology team discharged us. Structurally normal heart with PLSVC as a normal variant. Just another check some months after he is born.

@Eirth25 So glad that they’ve discharged you. Enjoy the rest of your pregnancy 🙂

Just an update, I had my little girl on 16th of July and she has just had a follow up heart echocardiogram. Obviously she still has the plscvc but everything else looks normal and she’s been completely discharged! For her at least it is just a variation of normal and should cause no problems!
