As per available reports about 12 relevant Journals, 10 Conferences, 2 National symposiums are presently dedicated exclusively to atrial septal defect and about 109 articles are being published on Atrial Septal Defect.
An atrial septal defect (ASD) is a hole in the septum, or muscular wall, that separates the heart’s two upper chambers (atria). An ASD occurs when part of the atrial septum does not form properly. Normally, the right side of the heart pumps blood that is low in oxygen to the lungs, while the heart’s left side pumps oxygen-rich blood to the body. When there is an ASD, blood from the left and right sides mix, and the heart generally does not work at its most efficient level. The risk of problems is greater when the defect is large (greater than 2 cm). Problems may include:
• Right heart enlargement (leading to right heart failure)
• Heart rhythm disturbances, including atrial fibrillation or atrial flutter, occur in 50 to 60 percent of all patients over age 40 with an ASD.
• Pulmonary hypertension (high blood pressure in the arteries that supply blood to the lungs). Blood normally flows from the left side of the heart to the right, but in patients with an ASD and severe pulmonary hypertension, the blood flow across the ASD can reverse (flow right to left).
As a result, oxygen levels in the blood will decrease, leading to a condition known as Eisenmenger syndrome . Leaking tricuspid and mitral valves as a result of enlargement of the heart.

Scope and Importance
In infants, small ASDs (less than 5 mm) will often not cause problems, or will close without treatment. Larger ASDs (8 to 10 mm), often do not close and may need a procedure. Important factors include the size of the defect, the amount of extra blood flowing through the opening, and whether the person has any symptoms. Some people with ASD may have other congenital heart conditions. These may include a leaky valve or a hole in another area of the heart.
The normal Heart has two sides, which are separated by a muscular wall called the septum. Each side of the heart also has two parts - the upper chamber called an atrium, and the lower chamber called a ventricle. An atrial septal defect (ASD) is an opening in the wall (the atrial septum) View Large Atrial Septal Defect (ASD) Illustration between the heart's two upper chambers (the right and left atria). An ASD is one of the defects referred to as "a hole in the heart. “Normally, the right side of the heart carries deoxygenated blood back into the heart and the left side carries oxygenated blood back out to the body. An ASD allows the oxygenated blood to pass from the left atrium, through the opening in the septum, into the right atrium causing the two to mix. This leads to increased Blood flow through the right side of the heart and lungs. Over time, this "extra" blood volume stresses the heart and causes the right atrium, ventricle and pulmonary arteries to dilate (become wider). This can eventually lead to heart failure, pulmonary hypertension or heart rhythm abnormalities. A "hole" in the wall that separates the top two chambers of the heart. This defect allows oxygen-rich blood to leak into the oxygen-poor blood chambers in the heart. ASD is a defect in the septum between the heart's two upper chambers (atria). The septum is a wall that separates the heart's left and right sides.
Atrial septal defect (ASD), which accounts for 8%-10% of congenital heart diseases, reflects the most common type in adults. Percutaneous transfemoral septal closure is the contemporary alternative to surgical closure. According to the American College of Cardiology Foundation, in 2010, the prevalence of CHD in Asia was 8.9 to 9.7 per 1,000 live births, whereas in Africa this figure was 1.1 to 3.5 per 1,000 live births.
