No upper bound. Close to the superior vena cava entrance.,2.Central type ASD: Ostiumstm secundum skndm ASD, the real atrial septal defect II. About 70%-75%. It is the most common. Often in the fossae fsi: ovalisvls . Diameter damt(r) about 15-30mm. circular or oval, atrial septum around the defect are complete. Relating rlet to the absence or deformity df:mti of the oval valve, unlike PFO.,3.Type Inferior vena vi:n cavak:v,About 7-12%, usually bigger one. located in posteroinferiorpstrnfrr of the atrial septum and foramen freimen ovale vel . Close to the superior vena cava entrance. Most of them are connected to the inferior vena cava.,4.Mixed type: Including two or more than two types of ASD combination of the three. Usually bigger one. Occuping most of the atrial septal defect. Very few residual rzdjul atrial septum. Even the whole Atrial septal defect, like functional single atrium.,5.Coronary sinus sans type,Aslo means unroofed coronary sinus syndrome.,conclusion: Central type ASD are most common.,1.Age, usually more than 3 years old 2.The diameter is greater than or equal to 5 mm and less than 36mm with the increase of right ventricular volume overload. 3.The distance of defect edge to the coronary sinus, superior and inferior vena cava vi:n kev and pulmonary vein are greater than 5mm, and to atrio-ventricular valve vlv are greater than 7mm. 4.The diameter of the atrial septum the diameter of the left atrial side of the occluder klu:dr . 5.No other deformities df:mtitis requiring surgery。,Indication of occlusionklu:n
