Atrial Septal Defect (ASD) is a defect between the two upper heart chambers (the atria). This defect allows mixing of oxygenated and deoxygenated blood, eventually causing right heart enlargement and high pressure in the lungs (pulmonary hypertension).
Moderate- to large-sized Atrial Septal Defect (ASD) causing right heart dilatation and raised pressure in the lungs should be closed. Closure can be performed either via percutaneous method using devices (through the femoral vein) or through open-heart surgery.
Small Atrial Septal Defect (ASD) with no chamber enlargement, raised lung pressure or other complications needs only to be followed up at the clinic.
This procedure is performed to close the ASD by inserting a device through the blood vessels in the groin (percutaneous transcatheter approach) which will close the ASD.
