What is Secundum Atrial Septal Defect?
Secundum atrial septal defect (ASD) is a common congenital heart defect that affects the structure of the heart. It occurs when there is an abnormal opening in the atrial septum, the wall that separates the two upper chambers of the heart, known as the atria. This opening allows oxygen-rich blood from the left atrium to flow into the right atrium, causing a mixing of oxygenated and deoxygenated blood.
ASD is considered to be a secundum defect because it primarily involves the central portion of the atrial septum. It is one of the most common types of congenital heart defects, accounting for approximately 10% of all cases.
Causes and Symptoms
The exact cause of secundum ASD is not fully understood, but it is believed to be a combination of genetic and environmental factors. Some studies suggest that certain genetic mutations may play a role in the development of ASD. Environmental factors, such as maternal exposure to certain medications or substances during pregnancy, may also increase the risk.
Most individuals with secundum ASD do not experience symptoms until later in childhood or adulthood. Common symptoms may include:
- Shortness of breath, especially during physical activity
- Fatigue or weakness
- Recurrent respiratory infections
- Heart palpitations
- Swelling in the legs, feet, or abdomen
Diagnosis and Treatment
Diagnosing secundum ASD typically involves a combination of physical examinations, imaging tests, and cardiac catheterization. An echocardiogram, a non-invasive test that uses sound waves to create images of the heart, is commonly performed to visualize the defect and assess its severity.
Treatment for secundum ASD usually involves a surgical procedure called cardiac catheterization. During this procedure, a catheter is inserted into a blood vessel and guided to the heart, where a device is placed to close the defect. In some cases, open-heart surgery may be necessary to repair larger defects.
Conclusion
Secundum atrial septal defect is a common congenital heart defect that affects the structure of the heart. While it may not cause symptoms in early childhood, it is essential to diagnose and treat ASD to prevent potential complications later in life. If you suspect you or your child may have an ASD, it is important to consult with a healthcare professional for proper evaluation and guidance.

Treatment Options for Secundum Atrial Septal Defect
Secundum atrial septal defect (ASD) is a common heart defect that affects the wall between the heart's upper chambers. If left untreated, it can lead to various complications. However, there are several treatment options available to manage this condition effectively.
