Objectives Discussing what causes endothelialisation insufficiency, then we can offer factual basis to closure surgery of ASD.Methods 18 canines were randomly divided into three groups,made 6 mm diameter atrial septal defect for each canine, what was guided by transthoracic echocardiography, then placed in different types of occluder in three group of canines, routinely given anti-infective and anticoagulant therapy after operation, 14 months later, put them to death and got the heart, separated the newborn endothelial tissue which was on the occluder in electron microscopy.
