Patients with small atrial septal defects and no related symptoms, pulmonary hypertension, or ventricular enlargement generally do not need specific medication. If symptoms do occur, interventional or surgical treatment should be chosen. Medication is necessary only if there is accompanying heart failure, pulmonary infection, or arrhythmias such as atrial fibrillation. In the case of infections like pneumonia or infective endocarditis, appropriate antibiotics or antiviral medications should be actively used. When heart failure occurs, medications to control arrhythmias, such as vasodilators, diuretics, and agents to control ventricular rate, are required.

Do infant atrial septal defects heal by themselves?

Atrial septal defect is a common congenital heart disease, accounting for about 1/1500 of newborns, and is most commonly found in infants and children. The impact of atrial septal defects on hemodynamics mainly depends on the amount of shunting. Some studies confirm that atrial septal defects smaller than six millimeters can close on their own without external intervention. Therefore, when an atrial septal defect is discovered, it is necessary to regularly recheck the cardiac echocardiography to determine the size of the defect. If the atrial septal defect decreases in size as the patient ages, there is a possibility of self-healing. If the area of the patient's atrial septal defect does not change or gradually increases, regular echocardiography rechecks are needed, and cardiac catheterization may be performed if necessary.

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.

Is a ventricular septal defect with pulmonary hypertension mild or severe?

The most common complication of atrial septal defect is pulmonary hypertension, which can be classified as mild, moderate, or severe. Generally, mild pulmonary hypertension is not a major issue and is not considered very serious. However, moderate to severe pulmonary hypertension often accompanies repeated coughing, shortness of breath after exercise, or difficulty breathing. This situation is relatively serious and it is advisable to undergo surgery as soon as possible. If the condition reaches a severe stage, pulmonary hypertension could continuously increase. Furthermore, in patients with severe pulmonary hypertension, closing the atrial septum can lead to severe breathing difficulties and increased shortness of breath. Therefore, it is crucial to closely monitor patients with pulmonary hypertension.

Can someone with an atrial septal defect get pregnant?

Whether patients with atrial septal defects can become pregnant depends on the following factors: 1. Whether the patient normally has symptoms. 2. Whether the echocardiography indicates heart enlargement or pulmonary hypertension. 3. The size of the atrial septal defect. 4. Whether there is a combination of arrhythmias such as atrial flutter or atrial fibrillation, and complications such as pulmonary hypertension or heart failure. For those without symptoms, and where the defect does not cause pulmonary hypertension or right heart enlargement, choosing to become pregnant is possible. Complications are not common in pregnant women with isolated atrial septal defects without pulmonary hypertension. Studies have shown that the incidence of complications in pregnant women, whether the defect is repaired or not, is relatively low. If the patient has related arrhythmias and complications, it should be closely monitored, because the cardiovascular system of the mother undergoes changes during pregnancy, leading to increased cardiac workload and a higher burden on the heart, which in turn can increase the incidence of arrhythmias. For women who are already at high risk of atrial flutter or fibrillation, this risk can increase further. Additionally, pregnant women are in an older physiological state, making it easier to form blood clots, and for those with atrial septal defects, the risk of paradoxical thrombosis increases.

How severe is an atrial septal defect considered to be?

Atrial septal defect (ASD) is a relatively common congenital heart disease in clinical practice. From a medical perspective, the severity of ASD depends on whether the patient is an adult or a child. For adults with ASD, generally speaking, defects larger than 20 millimeters are considered large atrial septal defects, which are more severe. If the defect size is between 10 and 20 millimeters, it is often classified as a moderate atrial septal defect. Defects smaller than 4 millimeters are considered small atrial septal defects. Generally, small and moderate atrial septal defects are not severe. For children, an atrial septal defect larger than 10 millimeters is considered a large atrial septal defect, which is more severe. Sizes between 5 and 10 millimeters are classified as moderate atrial septal defects. Defects smaller than 5 millimeters are considered small atrial septal defects, which generally are not severe.
