In the heart, there are four chambers-two lower chambers are known as ventricles and upper chambers are known as atria. In the healthy heart, blood passes to right ventricle and then to lungs for receiving oxygen. The blood that is filled with oxygen returns to left atrium and after that to left ventricle. After that, blood is pumped out of the body through aorta. In this process, both the chambers are separated by thin shared wall, causing the condition of atrial septum.

If the condition is showing no symptoms, no treatment is required. If the defect is large, surgical measures are taken. Recently, a procedure has developed that involves treating the atrial septal defect without surgery. In the procedure, ASD closure device is placed into the heart through catheters, tubes. However, only drawback with this procedure is that procedure cannot be performed in all patients. For reducing the risk of infective endocarditis straight away after the surgery, prophylactic antibiotics are given.
