Atrial Septal Defect (ASD) ➢ ASD is the most frequent congenital lesion . It is often not diagnosed until adult life, because it rarely produces symptoms in childhood ➢ Three types of atrial septal defect are classified on an anatomic basis: Ostium primum ASD 原发孔型房缺 Ostium secundum ASD 继发孔型房缺 Patent foramen ovale （PFO）卵圆孔未闭 ➢ All three types are associated with a left-to-right shunt at the atrial level and volume overwork of the right ventricle
