Persistent Ductus Arteriosus (PDA)

Persistent Ductus Arteriosus (PDA)
Persistent Ductus Arteriosus (PDA) is the name of the tube that carries blood between the aorta and the pulmonary artery in the foetus.

This tube normally closes at or shortly after birth. Sometimes, however, the mechanism of closure does not work, and the connection continues to remain open this causes blood to enter the lungs and cause more work for the heart & lungs.


If the PDA is small, it doesn't have to be closed because it doesn't make the heart and lungs work harder.
