Subtypes There are numerous types, differentiated by the extent of the defect. These types are: * Type I: simple defects leading to communication between the ascending aorta and pulmonic trunk * Type II: defects that extend to the origin of the right pulmonary artery * Type III: anomalous origin of the right pulmonary artery from the ascending aorta It is also classified as simple or complex. Simple defects are those that do not require surgical repair, occur with no other defects, or those that require minor stright-forward repair (ductus arteriosus, atrial septal defect). Complex defects are those that occur with other anatomical anomalies or require non-standard repair.
