  • Atrial septal defect

    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.

    Among 4006 scanned fetuses and neonates, there were 75 congenital heart defects, including 12 major defects. The observed prevalence for all congenital heart defects was 18.7 (95% confidence interval, 14.8-23.5) per 1000 births, and the prevalence for major defects was 3.0 (95% confidence interval, 1.6-5.2) per 1000 births. The most common defects were ventricular septal defects (n = 47 [62.7%]), atrial septal defects (n = 14 [18.7%]), tetralogy of Fallot (n = 4 [5.3%]), and hypoplastic left heart syndrome (n = 3 [4.0%]).

    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.
