A mild atrial septal defect, such as one smaller than 3mm, allows for a normal life without any impact. In fact, some people only discover this condition during medical exams in their seventies or eighties. Therefore, it is safe for these individuals to travel to high altitudes. However, a larger atrial septal defect often causes symptoms like tightness in the chest, palpitations, and difficulty breathing after hypoxia or intense exercise. These patients have poorer compensatory abilities and are advised against going to high altitudes to avoid high altitude sickness. If such patients need to go to high altitude, it is recommended that they consider surgery before doing so.

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.

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.

The difference between ventricular septal defect and atrial septal defect

The difference between a ventricular septal defect and an atrial septal defect mainly lies in their locations. A normal heart is divided into four chambers, which are the left ventricle, right ventricle, left atrium, and right atrium. Each chamber is separated by a septum, much like walls between rooms in a house. Due to certain reasons, such as congenital heart defects, there may be openings or defects in these walls, known as septal defects. An atrial septal defect refers to a defect between the right atrium and the left atrium, whereas a ventricular septal defect pertains to a defect between the left and right ventricles. The murmur of atrial septal defects is relatively softer, as the pressure difference between the atria is smaller, and the defect is located higher up. In contrast, the murmur of ventricular septal defects is louder due to the greater pressure difference between the ventricles and is located lower down, approximately between the third and fourth ribs. The murmur of atrial septal defects is found between the second and third ribs. Moreover, since the pressure difference in ventricular septal defects is greater, the impact on the heart is relatively more significant.

Atrial septal defect should be consulted with the Department of Cardiology.

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.

Can atrial septal defect heal by itself?

Atrial septal defect is a relatively common congenital heart disease in infants and toddlers. It is indeed possible for a child's atrial septal defect to close on its own. Some atrial septal defects can close as the child grows. Depending on the severity, atrial septal defects can be categorized into small defects. Generally, if the defect is less than 5 millimeters, it is possible for the defect to close as the child develops. If it has not closed by the age of two, it generally will not close on its own thereafter.
