In pediatric atrial septal defect cases, when is surgical correction typically anticipated?

• A. Surgical correction anticipated either at 3-6 months or 6-18 months.
• B. Immediately after birth.
• C. Not performed; managed with observation only.
• D. Only after age 5 years

Answer: (A)

The key idea is when to close a pediatric atrial septal defect (ASD) based on how much blood is shunted and how it is affecting the heart and lungs. If the defect is large and the left-to-right shunt is significant, the goal is to prevent progressive right-heart dilation and potential early pulmonary vascular changes, so repair is planned in infancy rather than waiting. In practice, surgical (or device) closure is typically anticipated within the first year of life—often around 3–6 months or by 6–18 months—depending on the child’s growth, symptoms, and echocardiographic findings.

Small ASDs that are unlikely to cause problems may be observed, since many close spontaneously in the first year. Delaying repair beyond infancy isn’t usually favored when the defect is hemodynamically significant, as delaying can increase the risk of irreversible pulmonary vascular disease. Immediate repair after birth isn’t the norm, and waiting until age 5 years is generally not preferred if closure is indicated.
