Atrial septal defect is a common congenital heart disease in childhood, and it is also the most common congenital heart disease in adulthood. The incidence rate of atrial septal defects is about 1/1500 live births, accounting for 5%-10% of all congenital heart diseases, and it is more common in females. Most children with atrial septal defect, in addition to being prone to respiratory infections such as colds, may have no obvious symptoms and their activities are not limited. It is generally not until adolescence that symptoms like shortness of breath, palpitations, and fatigue appear. Patients with atrial septal defects should seek treatment in departments such as cardiology, cardiovascular surgery, thoracic surgery, or pediatric cardiology.

How to treat atrial septal defect

Typical cardiac murmur ECG and X-ray findings may suggest the presence of an atrial septal defect. An echocardiogram can confirm the diagnosis, and it should be differentiated from conditions such as anomalous pulmonary venous return, pulmonary valve stenosis, and small ventricular septal defects. For the treatment of atrial septal defects, in adult patients, if echocardiographic evidence of increased right ventricular volume load is present, the defect should be closed as soon as possible. Treatment options include interventional and open-heart surgical procedures. Before the implementation of interventional surgeries, all cases of simple atrial septal defects that have caused hemodynamic changes, with signs of increased pulmonary blood flow, enlargement of the atria and ventricles, and corresponding ECG findings, should undergo surgical treatment. In older patients with severe pulmonary hypertension, surgical treatment should be approached with caution.

Causes of atrial septal defect in babies

Atrial septal defect is a relatively common congenital heart disease, which is related to genetic factors, environmental pollution, exposure to radiation during pregnancy, and viral infections. The severity of atrial septal defect in babies varies. Babies with mild symptoms are generally not easily detected, often being discovered during physical examinations or when other diseases prompt stethoscopic evaluation, revealing heart murmurs. Babies with severe conditions may experience significant hypoxia after birth, exhibiting cyanosis, rapid breathing, cyanotic lips, weak crying, reduced feeding, with symptoms becoming more pronounced during crying. These babies have lower immunity, making them prone to recurrent respiratory infections, and in severe cases, can lead to heart failure. Therefore, it is important to provide extra care in daily life, ensure proper nutrition, enhance physical health, and opt for surgical correction as soon as conditions permit.

What should be paid attention to daily with an atrial septal defect?

If the patient has an atrial septal defect, it is advised that the patient should adhere to a light diet and regularly visit the hospital for electrocardiogram and echocardiography checks. If the defect is relatively large, I personally recommend surgical treatment for the patient, as it can effectively alleviate the current condition. After all, while drug treatment has some effect, there is a risk of recurrence. Surgery can permanently treat atrial septal defects and improve the patient’s symptoms. If the patient experiences difficulty breathing, this needs to be addressed. Additionally, it is important to keep warm, avoid catching cold, and monitor changes in the patient’s heart rate, blood pressure, and pulse.

Can someone with atrial septal defect travel by airplane?

Atrial septal defect is a relatively common congenital heart disease in daily life. Many patients with atrial septal defect often ask if they can fly on planes. This depends on the specific condition. If the atrial septal defect is combined with severe cardiac damage, such as heart failure, then flying is definitely not allowed. However, if the atrial septal defect is mild, not severe, without clinical symptoms or cardiac damage, then it is indeed possible to fly. It is recommended for those in this condition to visit a cardiology outpatient clinic at a hospital and ask a doctor to make an assessment.

Is atrial septal defect common?

Atrial septal defect accounts for about 20%-30% of all congenital heart diseases and is more common in females. Many cases are mild in children and are not discovered until adulthood. Atrial septal defects can be classified based on anatomical abnormalities into patent foramen ovale, primary atrial septal defect, and secondary atrial septal defect. A patent foramen ovale generally does not cause shunting between the two atria. A primary atrial septal defect is located at the lower part of the atrial septum, is semicircular in shape, and is often larger, frequently associated with malformation of the mitral or tricuspid valves resulting in regurgitation. A secondary atrial septal defect is situated in the middle of the atrial septum at the fossa ovalis or near the superior and inferior vena cava. The symptoms of an atrial septal defect vary with the size of the defect; minor cases may be asymptomatic, while severe cases can result in heart failure.
