Atrial septal defect is one of the commonest congenital cardiac anomaly present in adulthood. An outsized ostium secondum that persists in adulthood is a cause for ASD. It is commonly regarded as a __ampersandsignlsquo;hole__ampersandsignrsquo; in the septum in the region of foramen ovale and ostium secondum. It is the common form of atrial septal defect, present in 8 out of 10 congenital heart disease. It occurs as a result of defects in septum primum and septum secondum viz. inadequate formation of septum secondum or excessive resorption of septum primum thereby leaving ostium secondum incompletely covered.
