What Is an Atrial Septal Defect?
ASD is a common congenital heart condition where the septum — the wall separating the heart two upper chambers — has a hole present from birth. This allows blood to flow abnormally between the chambers, which over time can strain the heart and lungs if left untreated.
How Is ASD Closure Done?
A catheter is guided from a vein, typically in the groin, into the heart
Using imaging guidance, the catheter is positioned at the site of the defect
A small umbrella-shaped closure device is deployed, opening on both sides of the septum
The device seals the hole, and heart tissue gradually grows over it permanently
Who Needs ASD Closure?
Patients, often young adults, diagnosed with a moderate-to-large ASD
Patients experiencing symptoms such as fatigue, breathlessness, or irregular heartbeat linked to the defect
Patients whose defect anatomy is suitable for a catheter-based (rather than surgical) closure
What Are the Risks of ASD Closure?
Device migration or improper positioning
Irregular heart rhythms
Bleeding or vascular access complications
Rare risk of injury to surrounding heart structures
Frequently Asked Questions
Is ASD only diagnosed in children?
No — many ASDs are diagnosed in adulthood, sometimes incidentally, since smaller defects can go unnoticed for years.
Does every ASD need to be closed?
Not necessarily — small defects causing no symptoms may simply be monitored. The decision depends on the defect size and its effect on heart function.
