Patent Ductus Arteriosus

General Considerations

  • Persistent communication between the thoracic aorta and the pulmonary artery by the ductus arteriosus
  • In fetal life, ductus carried blood from the pulmonary artery to the aorta, essentially bypassing the fetal lungs
  • The ductus usually closes functionally within a few hours after birth
    • If the ductus remains patent beyond 3 months, it is considered abnormal
  • The effect of the left-to-right shunt will depend on the size of the shunt and the pulmonary vascular resistance
