Surgery is not recommended for newborns, asymptomatic patients with congenital patent foramen ovale, or those with contraindications to surgery. 1. It is normal for newborns to have a small foramen ovale, most of which can be closed naturally within six months after birth, and a few of which can be healed before the age of 3 years. 2. Asymptomatic patients with congenital patent foramen ovale can be treated without surgery. Usually, there is no obvious heart murmur, and the electrocardiogram and chest X-ray may not be abnormal, and at this time, the patient does not need to undergo any special treatment. If conservative treatment with drugs is performed, drugs including anticoagulants such as warfarin and antiplatelet agents such as aspirin can be used. 3. For patients with contraindications to surgery, such as severe heart failure, respiratory failure, severe cerebral infarction and other cardiovascular and cerebral vascular diseases, severe liver failure, uremia and other hepatic and renal diseases, it is not recommended to operate, but only through conservative treatment and regular disease screening. Foramen ovale is a type of atrial septal defect and the most common type of congenital heart disease. Many adults suffer from atrial septal defects, and surgery is usually required to prevent the occurrence of stroke and other diseases. Common treatments include surgical repair and interventional occlusion. Interventional occlusion has gradually replaced surgical treatment in most cases. If the diagnosis of patent foramen ovale is confirmed, it is recommended to consult a specialist in a timely manner, follow the doctor’s instructions for regular treatment, avoid unauthorized use of medication, and under the guidance of the doctor to determine whether surgical treatment is needed and the treatment plan.
