It is a simple and common type of ASD with shunt from LA to RA. Usually asymptomatic and acyanotic in children and young adults.

Atrial Septal Defect Treatment

• Appropriate health care: Referral to a cardiologist for evaluation
• Majority of small ASDs will close spontaneously; however, close follow-up is warranted
• Closure is usually delayed until preschool age (2–4 years), except for large defects to be repaired earlier.
• Closure via percutaneous transcatheter device or surgery
