What are the symptoms of patent ductus arteriosus?

The size of the patent ductus arteriosus will affect the type of symptoms, the severity of symptoms and when they occur.

A child with a small patent ductus might not have any symptoms, and your child's doctor may only discover the defect by hearing a heart murmur.

Babies with a larger patent ductus may have the following symptoms:

  • fatigue
  • sweating
  • rapid breathing
  • heavy breathing
  • congested breathing
  • disinterest in feeding or tiring while feeding
  • poor weight gain

What are the causes of patent ductus arteriosus?

Almost all children have a small connection between the aorta and pulmonary artery at birth. It is not known why some children have a connection that doesn’t close.

Boston Children’s is so much more than a hospital—it’s a community of researchers, clinicians, administrators, support staff, innovators, teachers, patients and families, all working together to make the impossible possible. ”
