• A ductus arteriosus is a vascular fetal structure that usually closes in the first 48 hours after birth.
• Persistence of the ductus arteriosus can result in heart failure, increased pulmonary pressures, and endarteritis.
• The incidence and sequelae of a patent ductus arteriosus (PDA) are more significant in premature infants than infants born at full-term.
• Clinical history and presentation can vary significantly depending on age of the child and the size of the ductus. Patients may be entirely asymptomatic or have signs and symptoms of heart failure and haemodynamic instability.
• Treatment options vary depending on the age of the patient and the size of the ductus. Practice may vary significantly between institutions.
