Atrial Septal Defect Types And Overview

Atrial Septal Defects (ASDs) can be categorized based on their size. Defects measuring 6mm or less are considered small, those between 6-12mm are classified as moderate, and defects larger than 12mm are regarded as large. In addition to size classification, ASDs can also be divided into primary and secondary types. The primary type is associated with endocardial cushion defects, while the secondary type can further be classified into subtypes such as sinus venosus (superior and inferior vena cava types), secundum (central type), or mixed forms.

Understanding The Impact Of ASD Size

Small atrial septal defects often have minimal impact on a child's physical development and may even close naturally within the first two years of life. However, moderate to large defects are less likely to close on their own. These types of defects, especially when located in favorable positions, can often be treated effectively through minimally invasive procedures such as cardiac catheterization, which typically does not interfere with the child's overall growth and development.

Medical Management And Treatment Options

When it comes to managing atrial septal defects, early diagnosis and monitoring are key. While small defects may not require immediate intervention, regular follow-ups with a pediatric cardiologist are essential. For larger or symptomatic defects, treatment options may include surgical repair or device closure, both of which have high success rates and excellent long-term outcomes.
