Atrial Septal Defect Explained: Types and Device Closure

Описание: An Atrial Septal Defect (ASD) is a congenital heart defect in which there is an opening between the two upper chambers of the heart (atria). This opening allows abnormal blood flow from the left atrium to the right atrium, which can gradually lead to enlargement of the right side of the heart if left untreated.

In this video, we explain what an atrial septal defect is, the different types of ASD, how it is diagnosed, and how modern minimally invasive device closure offers safe and effective treatment—especially for children.

Key points covered
What an atrial septal defect (ASD) is and how it affects the heart
Types of ASD: sinus venosus, ostium secundum, and ostium primum
Why ostium secundum ASD is most suitable for device closure
Common symptoms of ASD in children and adults
When ASD requires closure due to heart enlargement
How ASD device closure is performed using cardiac catheterization
Benefits of minimally invasive treatment over open surgery

Diagnosis and treatment overview
ASD may be detected in childhood or adulthood
Symptoms in children may include poor growth, recurrent chest infections, or a heart murmur
Medium to large ASDs causing right heart enlargement are advised for closure
Device closure is done via leg veins using an atrial septal occluder
The procedure usually takes 1.5–2 hours under intravenous sedation
Most patients are discharged the next day

Recovery and follow-up
Blood thinners are prescribed for about six months
Limited physical activity for 1–2 weeks after the procedure
Children can return to school and normal play soon after
Regular follow-up ensures safe healing and excellent outcomes
