Incidental detection of patent ductus arteriosus during cardiac surgery in adult patients: A case series

Patent ductus arteriosus (PDA) is an inborn heart defect in which the ductus arteriosus (i.e., a vascular structure between the pulmonary artery and aorta that usually closes shortly after birth) remains open. Because most patients with PDA are diagnosed and treated when they are infants, this is a relatively rare congenital heart defect among adults. Herein, we present the cases of PDA in adults, which were detected during cardiac surgery.
