Abstract：ObjectiveTo investigate thesafety，feasibilityand efectiveness simple ultrasound-guided percutaneous atrialseptaldefect（ASD）closureinchildren.MethodsAtotal8Ochildrenwhounderwentinterventionalclosureafter strictcardiac ultrasound assessment were included.They were divided into the X-ray group （O cases）andtheultrasound group（6Ocases）basedonthe guiding method.Thepreoperative clinicalcharacteristics，surgical indicatorsand postoperative outcomes werecompared between the two groups.ResultsCompared with the X-ray group，the proportion preoperative pulmonaryvalve insuficiencyandmitralvalveinsufficiencywere lowerintheultrasound group，andthecardiothoracicratio was smaller （ P<0.0 ）.All surgeries in both groups were successfully completed. Compared with the X-ray group，the defect diameterandthediametertheusedoccluderwere smalerintheultrasoundgroup，andthedistances fromtheopposite side edgeand the inferior vena cava entrance werelonger in the ultrasound group （ P<0.0 ）.Compared with the X-ray group， the postoperative hospital stayintheultrasound groupwasshorter，thediference in white bloodcellevels beforeandafter surgerywasgreater，thepostoperativerightatrialdiameterand postoperativerightventriculardiameter were larger，the postoperativereductionrate right ventriculardirameter and the incidence postoperativearrhythmia was lower（ P<0.0 ） Therewas no statisticallysignificant diference intheincidenceoluder endothelializationwithin 6months after surgery betweenthe two groups.ConclusionSimpleultrasound-guided ASDclosure is safe and efective.Thesurgical success rate is not inferior to that X-ray-guided ASD closure，and the postoperative hospital stay is shorter.

房间隔缺损（atrial septaldefect，ASD）是指在胚胎发育过程中，房间隔的发生、吸收和融合出现异常，导致左、右心房之间存在血流交通的一种心脏畸形，一般无明显症状，通常因心脏杂音或超声筛查到心房分流而就诊。（剩余9485字）
