Left to Right Shunts: Patent Ductus Arteriosus (PDA)

The ductus arteriosus is an integral part of the normal fetal circulation allowing blood to bypass the fetal heart in utero. Failure of the ductus to close at birth can lead to a variety of clinical presentations depending on the duration, size, and co-existing congenital abnormalities. PDA accounts for 10% of congenital heart defects but is relatively rare in adults.

  • To identify and recognize the physical findings associated with patent ductus arteriosus
  • To interpret angiographic and hemodynamic data associated with patent ductus arteriosus
