Atrial septal defect (ASD) is a fairly common congenital heart disease in pediatric cardiology. For infants and young children, atrial septal defects can be categorized based on their size into three types: A large atrial septal defect typically refers to a defect larger than 10 millimeters. A medium atrial septal defect generally refers to a defect that ranges from 5 to 10 millimeters. A small atrial septal defect usually refers to a defect that is less than 5 millimeters. Therefore, for an infant or young child, an atrial septal defect measuring 12 millimeters would indeed be considered quite severe.

Can a ventricular septal defect heal itself?

Traditional views suggest that the best age to close atrial septal defects (ASDs) is between four and five years old, during preschool. The possibility of spontaneous closure of atrial septal defects larger than 8 millimeters in diameter is very low. If the defect is less than 4 millimeters, there is a possibility of healing. Currently, it is advocated that if an atrial septal defect still exists after the age of one year, and there is evident systolic murmur and fixed splitting of the second heart sound, or if heart catheterization and echocardiography show left-to-right shunting greater than 1.5:1, indicating a defect diameter of five to six millimeters or more, early surgery should be pursued to stop the left-to-right shunt to avoid causing pulmonary hypertension and endocarditis.

Postoperative complications of atrial septal defect intervention surgery

Atrial septal defect is a relatively common congenital heart disease in clinical practice. Minimally invasive interventional treatment can effectively address atrial septal defects and generally leaves no surgical scars. The complications of atrial septal defects can be analyzed from the following aspects: First, puncture complications. Atrial septal defects require the puncture of the femoral vein. A small number of patients may experience complications such as arteriovenous fistula, pseudoaneurysm, or hematoma at the puncture site. Generally, these complications are not serious and do not endanger the patient's life. Second, complications from dislodged occlusion devices. If the occlusion device becomes dislodged, it can lead to serious complications, including obstruction of the relevant blood vessels. Third, hemolytic reactions. A small number of patients may develop hemolytic reactions to the occlusion device. Such complications are also quite serious; however, they are very rare in clinical practice and do not require excessive concern.

Symptoms of an infant's room septal defect

Symptoms of ventricular septal defect in infants are as follows: 1. Symptoms: If the mother had intrauterine infections within the first three months of pregnancy, was exposed to significant amounts of radiation, took teratogenic medications, or had metabolic disorders, these factors could contribute to the condition. The patient is prone to recurrent respiratory infections and exhibits symptoms of palpitations, shortness of breath, fatigue, and excessive sweating. If these symptoms worsen after physical activity or crying and are accompanied by cyanosis, congenital heart disease should be considered. Cyanosis can intensify during severe crying episodes, pneumonia, or heart failure in infants, and may be accompanied by a hoarse voice. 2. Physical signs: Notable findings include a bulging in the precordial area and diffuse apical impulse. A soft, systolic murmur can be heard between the second and third ribs along the left margin of the sternum.

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.

Can atrial septal defect of the patent foramen ovale type heal itself?

This disease is a congenital heart disease, and it is recommended that the patient undergo a cardiac echocardiography. If symptoms such as palpitations and chest tightness occur, and distinct murmurs can be heard in the precordial area, surgical treatment is sometimes advised. After all, an atrial septal defect can lead to certain conditions, especially in children who are prone to pediatric pneumonia or bronchitis, which can affect their growth and development. Currently, surgical treatment is the main approach. If the issue is not very serious, the defect might heal on its own as the child grows, but this possibility is relatively small. In most cases, surgery is recommended.
