Atrial septal defect (ASD) is a heart defect that is present at birth (congenital). As a baby develops in the womb, a wall (called the interatrial septum) forms that divides the upper chamber into a left and right atrium. An abnormal formation of this wall can result in a hole that remains after birth.This defect allows oxygen-rich blood to leak into the oxygen-poor blood chambers in the heart. The septum is a wall that separates the heart's left and right sides.
A retrospective analysis of records of 10,641 patients over a five-and-a-half year period was done. A prevalence of 26.4 per 1000 patients was observed. VSD (ventricular septal defect) was the commonest lesion (21.3%), followed by ASD (atrial septal defect) in 18.9% and PDA (patent ductus arteriosus) in 14. 6%. Tetralogy of Fallot was the commonest cyanotic heart disease (4.6%). Maximum number of children with heart disease (82.9%) were diagnosed between 0-3 years of age.
There are no known medications that can repair the hole.Surgery may also be recommended for an adult who has many or severe symptoms. Surgery involves fixing the hole and may be done through cardiac catheterization or open-heart surgery. After surgery, follow-up care will depend on the size of the defect, person’s age, and whether the person has oTreatment ther birth defects.
