Atrial Septal Defect of 1.7mm: How Serious Is It?

An atrial septal defect (ASD) measuring 1.7mm is generally considered to be a minor condition with minimal impact on overall health. The size of the defect results in a very small shunt, meaning the abnormal flow of blood between the heart's chambers is negligible. In most cases, especially in young children, this type of defect does not interfere with growth, development, or normal heart function.

Understanding the Impact of a 1.7mm ASD

Because the shunt is small, the amount of extra blood flowing through the right side of the heart and into the lungs is minimal. This means that the heart and lungs are not significantly overworked, and symptoms are unlikely to develop. In infants and toddlers, a defect of this size may not require immediate intervention and can often be monitored over time.

Recommended Approach for Young Children

For younger children, especially those under the age of five, doctors often recommend a "watchful waiting" approach. This involves regular follow-up appointments every 3 to 6 months to monitor the defect using echocardiography. In many cases, small ASDs like this one can close on their own as the heart continues to grow and develop.

Options for Older Patients

However, if the child is over five years old and the defect remains open, the chances of spontaneous closure become much lower. At this stage, medical professionals may suggest a minimally invasive procedure to close the defect. This type of intervention is typically safe and effective, with a quick recovery time and low risk of complications.

In conclusion, while a 1.7mm atrial septal defect is not considered serious, it's important for parents to follow up with a pediatric cardiologist to ensure proper monitoring and determine the best course of action based on the child's age and overall health.
