Hi doctor,
I am pregnant with MCMA twins. We have been told that one twin has a reversed A wave. What possible outcomes can this have for the twin? Please explain. Thank you.
Hi,
Welcome to icliniq.com.
I read your query and can understand your concern. A reversed A wave in Doppler is associated with very high chance of trisomy in the baby. The genetic abnormalities associated with this maybe even fatal. Since monochorionic monoamniotic twins (MCMA twin) are usually monozygotic that is they share the same genetic material and hence the other baby may also be affected. I suggest you to get the other baby tested too. In case the results are normal for the other one, you could try going for selective fetal reduction procedure. Through this way you could at least have one healthy baby. Hopefully everything turns out well for you. All the best.
