In neonates with unclosed ductus arteriosus, which accounts for 10% of all cases of congenital heart disease, the preferred treatment is interventional therapy. In some pediatric patients, such as those with more obvious heart failure symptoms, it is also necessary to combine anti-heart failure treatment with indomethacin therapy within one week after birth, but still 10% of patients eventually require surgery, and interventional treatment is also preferred for patent foramen ovale.
