摘　　要：目的:评价实时三维经胸超声心动图(TTE)指导房间隔缺损(ASD)封堵术的可行性和作用。方法:术前经临床及超声筛选符合经导管封堵适应证的ASD患者24例(男15例,女9例),在TCASD术中以RT-3DE监测引导ASO的置入。结果:术前实时三维超声心动图测量房间隔缺损面积(26.43±7.24)cm2,释放封堵器腰部面积(27.02±6.87)cm2,二者间无统计学差异(t=1.78,P>0.05),但二者具有良好相关性(r=0.671,P<0.05)。随访所有患者,术后封堵器位置固定,无残余分流。结论:RT-3DE在TCASD术中可以实时监测引导封堵器的置入和释放,是指导ASD封堵的可行、有效、简便方法。Objective：To evaluate the feasibility and effect of real time three dimensional transthoracic echocardMgraphy （RT-3DE） on atrial septal defect （ASD）. Methods： 24 patients （male 15, female 9） indicated for ASI） according to the clinical and echocardiography examination were studied, During the transcatheter closure of atrial septal defect（TCASD）procedure, all patients were used by real time three - dimensional echocardiography in closure of atrial septal defect using Amplatzer septal occluder. Results： The area of ASD measured by RT - 3DE before occlusion was （26.43 ± 7.24）cm^2, the waist size of released occluder was （27.02 ± 6.87）cm^2, Fine correlation was existed between the size of ASD measured by TTE and the size of selected occluder, but the differences had not significance. （r = 0. 671, t = 1.78）. Occluder was firmly fixed without falling of in all patients. Conclusions：The placement of ASD occlusion could be monitored and guided by RT- 3DE successfully and optimally during TCASD procedure. RT- 3DE is a feasible, effective and simple method for guiding ASD occlusion.
