Patent ductus arteriosus (PDA)

on 2.9.08 with 0 comments



  • ductus arteriosus remains open after birth

  • 90% are isolated defects

  • you hear a continuous “machinery” murmur that is loudest with the second heart sound

  • must be treated because left ventricular pressure is being forced on the pulmonary microvasculature

  • if this is superimposed on other conditions, the PDA might be beneficial, and oxygen administration may close the ductus and kill the baby
