Atrial Septal Defect is a kind of Congenital Heart Defects (CHD) in which a hole is present in the wall (septa) that separates the two upper chambers of the heart (atria). It causes the leakage of oxygen rich blood directly from the left side chamber to the oxygen poor blood in the right side chamber.
