| Turner syndrome | Chromosome X monosomy | 25-45 |
| 22q11.2 deletion syndrome | Chromosome 22q11.2 (TBX1) | 70-75 |

Can you see heart defects on ultrasound?
Ultrasound technicians are diligent about getting clear pictures of the heart. “If the images are unclear or incomplete on the first attempt, we bring the patient back in a couple weeks to try again,” Dr. Chao says. “We are able to detect the majority of major heart defects with ultrasound.”
How does a baby’s heart develop?
Your baby’s heart develops from early in pregnancy through – and even after – birth. Two heart tubes have formed in the embryo. The two tubes fuse and blood flows through this tubular “heart” as it begins to beat. The sections of this tube will go on to form all the structures of the future heart.
What happens when a baby has a heart defect at birth?

The baby may appear ashen, have rapid and difficult breathing and have difficulty feeding. This heart defect is usually fatal within the first days or month of life unless it’s treated.
What causes heart malformations in babies?
Other birth defects – a baby affected by certain birth defects, such as Down syndrome, is more likely to have malformations of the heart. Maternal illness – illness of the mother during pregnancy (for example, rubella – now rare) may increase the risk of congenital heart disorders.
What does it mean when the heart does not grow properly?
Summary Sometimes, during fetal development, the heart and blood vessels do not grow properly.
