ABSTRACT

Objective To evaluate the clinical effect of interventional occlusion for atrial septal defect(ASD) with domestic occluder by X-ray in combination with echocardiography.Methods 38 patients with ASD were all implanted with domestic occluder.The imageological data before and 6 months after treatment were analysed and compared.Results There were no residual shunts after interventional treatment.The heart surface area,right inferior pulmonary artery diameter,the base lines of pulmonary cone,the diameters of pulmonary trunk and the degree of protrusion of pulmonary cone were all decreased after operation(P
