Is there sequela in operation of atrial septal defect of infant heart

Atrial septal defect (ASD) is one of the most common congenital heart diseases in infants. Interventional therapy is the first choice for surgical treatment of ASD. It is a minimally invasive surgery with little injury, low risk, high success rate and almost no sequelae. If the defect surface of atrial septal defect is relatively large, it is not suitable for occlusion, it must be treated by thoracotomy. This method has large damage, complicated process, relatively low success rate, and easy to show sequela such as arrhythmia and heart failure. Therefore, if you want to reduce sequela, it is best to choose the best age for treatment. Generally, 2 to 5 years old is the best age for surgical treatment of atrial septal defect.
