Patent ductus arteriosus refers to the condition in infants where the ductal connection between the pulmonary artery and the aortic arch from the embryonic period remains open after the first year of birth. Generally, this duct is tubular or funnel-shaped and most cases can be treated minimally invasively. Surgical treatment is considered only if there are severe adhesions involving the aorta or pulmonary artery, or there are developmental issues. Therefore, patent ductus arteriosus can be treated with minimally invasive surgery, and most cases are amenable to such treatment.
