All patients underwent femoral venipuncture catheterization examination to insert the occluder. Patent ductus arteriosus and ventricular septal defect needed femoral artery puncture operation. Aortic arch descending part or left ventricular ventriculography was performed before occlusion to further clarify the diagnosis and surgical indications and help choose occluder type. Angiography was repeated after surgery to judge the effect. Patients with atrial septal defect and ventricular septal were defected with conventional transthoracic echocardiography monitoring and evaluation.
