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 someone with an atrial septal defect go swimming?

Atrial septal defect is not uncommon in our daily lives. Many patients with atrial septal defects often ask their doctor if they can swim. This has to be analyzed based on specific circumstances. If the atrial septal defect is not severe, and it's just a minor atrial septal defect, generally it does not affect the patient's daily activities, such as swimming or running. However, if the atrial septal defect is severe, especially if it has led to heart failure and heart enlargement, in this situation, one should definitely not engage in strenuous activities such as swimming or running.

Does ventricular septal defect affect growth and development?

Because atrial septal defect is a type of congenital heart disease, if the patient's congenital heart disease is very severe, surgical treatment is needed. Atrial septal defect does have some impact on growth and development, as congenital heart disease can cause infections or pulmonary inflammation in patients, which can lead to developmental delays in children. Personally, I recommend that if it is a type of congenital heart disease, especially atrial septal defect, it is better to have surgery early, as this can avoid impacting growth and development. After the surgery, there are no sequelae, and it does not affect growth and development. However, not undergoing surgery can impact growth and development.

Does a ventricular septal defect make it easier to catch a cold?

Mild atrial septal defects generally permit a normal life and do not easily cause colds. However, when pulmonary hypertension and heart failure occur with an atrial septal defect, it can lead to pulmonary congestion. At this point, bacterial colonization occurs, making respiratory infections more likely to develop. However, the colds we often refer to are upper respiratory tract infections, and atrial septal defects generally do not cause a decrease in immune system function. However, if the upper respiratory tract infection is not treated promptly, it can lead to bronchitis, lung infections, etc., often exacerbating heart failure associated with the atrial septal defect. Therefore, while an atrial septal defect does not cause colds, patients with an atrial septal defect should address colds early to prevent the onset of heart failure triggered by the cold.

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.

Causes of infant room septal defect

Atrial septal defect is a relatively common congenital heart disease in infants and young children. The causes of atrial septal defects are not very clear, but modern medicine considers that it may be related to the mother having a cold during pregnancy or taking certain medications, or to certain physical and chemical factors during pregnancy. Generally, atrial septal defects are not inherited and are not largely related to genetics.
