Information for Parents


Doctors are unsure if early treatment should be offered to preterm babies to close the duct and reduce the risks of complications, or whether it would be safer to wait and see if the duct closes by itself.

You may have been approached by hospital staff about Baby-OSCAR. Please read this Parent Information Leaflet and discuss it with your friends and relatives if you wish. A member of the team caring for your baby will be happy to answer any questions you may have.

Research and clinical trials are an everyday part of the NHS. The people who do research are mostly the same doctors and other health care professionals who treat people. They want to find better ways of looking after patients. Sometimes there are uncertainties in the best care for patients – filling these knowledge gaps is vital, as research helps advance technologies and treatment, helping more babies survive.

Patent ductus arteriosus (PDA)

Patent ductus arteriosus is a common heart condition in babies. The duct (ductus) allows blood to bypass the lungs when the baby is in the womb. The duct usually closes in the first few days of life, when it is no longer needed. In some babies the duct does not close properly and this can lead to a variety of complications.

We’d like to thank the Children’s Heart Federation for compiling these short animations of a heart with a PDA versus a normal heart:
