Patent Ductus Arteriosus (PDA) is a condition that is prevalent in newborns wherein there is a persistent opening between the aorta and the pulmonary artery. It is a type of congenital heart defect that can lead to cardiac complications if not treated in time. There are various synonyms associated with PDA such as persistent ductus arteriosus, ductal-dependent lesion, patent arterial duct, and persistent patency of the ductus arteriosus. These synonyms are used interchangeably in medical reports, research papers, and clinical discussions to describe the same medical condition, which is often diagnosed by echocardiography and treated surgically, medically, or with intervention. Early detection and management of PDA are essential for ensuring the best possible health outcomes in affected newborns.
