目的探讨经胸超声心动图(TTE)及实时三维超声心动图在房间隔缺损(ASD)、室间隔缺损(VSD)封堵术中的临床应用价值。方法应用二维及三维超声心动图对2004-10—2005-10在天津市儿童医院就诊的24例继发孔ASD,10例VSD进行术前检查筛选,术中超声引导及术后随访检查。结果24例ASD患儿术前经TTE检测ASD直径(15·6±7·9)mm(5~26mm),所选Mmplatzer封堵器直径为(19·1±5·1)mm(5~32mm),23例封堵成功。室间隔膜部缺损直径:左室面缺损为5~9mm,右室侧口的直径为2·4~6·0mm,术中选择Amplatzer封堵器型号为4~6mm,10例VSD无残余分流。结论二维及三维TTE联合应用于ASD、VSD介入治疗具有很好的应用价值。

The application of color Doppler echocardiography in interventional treatment of atrial septal defect and ventricular septal defect

?? AbstractObjectiveTo evaluate the applied values of 2??dimensional echocardiography(2??DE) and real??time three??dimensional echocardiography(RT3DE) in closing atrial septal defects(ASD) and ventricular septal defects(VSD) with the Amplatzer devices. MethodsTwenty??four cases of secundum atrial defects(ASD) the ten case of ventricular septal defects(VSD) patients were studied by two??dimensional teansthoracic echocardiography and RT??3DE. ResultsIn 24 cases examined with trans??thoracic echocardiography (TTE), ASD mean diameter was (15.6??7.9)mm(5~26mm),The diameters of these devices were (19.1??5.1)mm(5~32mm).The device were successfully implanted in 23 cases.Size of VSD at the side of left ventricle (LV) from 5mm to 9mm,Size of VSD at the side of right ventricle (RV) from 2.4mm to 6mm.The diameters of these devices were 4mm to 6mm.The ten case of ventricular septal defects (VSD) patients no residual shunt was found. ConclusionTwo??dimensional transthoracic echocardiography and RT??3DE acts as a important role in successful opration and evaluating the short??term and long??term therapeutic effectiveness.
