Double aortic arch is a type of vascular ring heart defect. In a normal heart, the blood flows in from the body to the right atrium, goes into the right ventricle, and then goes to the lungs to pick up fresh oxygen. The blood returns to the left atrium, goes into the left ventricle, and goes out to the rest of the body through a very large artery called the aorta.
With a double aortic arch, the aorta branches into right and left tubes, instead of just being one large tube. The two tubes can circle around and compress the airways and/or esophagus.
While this condition may be detected in infancy, it is often found later.
Double aortic arch is a congenital defect. This means that the baby is born with the condition. It is not known exactly why the heart develops abnormally in some babies.
Symptoms may include:
These symptoms may be caused by other conditions. If your child has any of these, talk to the doctor right away.
Your doctor will ask about your child’s symptoms and medical history. A physical exam will be done. Tests may include:
Talk with your doctor about the best treatment plan for your child. Treatment options include:
If your child is having symptoms like difficulty breathing, surgery will be done. The goal of surgery is to tie off and close one of these extra branches. Once this is done, symptoms may improve right away or gradually over time.
Your child will have regular exams from a heart specialist.
There is no known way to prevent double aortic arch. Getting appropriate prenatal care is always important.
