摘　　要：目的:评价实时三维超声心动图(RT-3DE)在房间隔缺损介入封堵术前术后的应用价值。方法:RT-3DE检测187例房间隔缺损患者,分析缺损口的空间位置、大小和形态,并于封堵术后RT-3DE评估封堵器的位置及距主动脉瓣、二尖瓣和三尖瓣等周围组织和血管的距离。结果:RT-3DE能实时动态的显示房间隔缺损及其封堵器的位置、形态及其周围组织的关系,其中25例缺损口的下腔静脉端未见残端回声,5例缺损口最大间距为45 mm以上,且缺损口的心房顶部端和下腔静脉未见明显残端回声,1例因缺损处为筛孔状改行外科手术。结论:RT-3DE在明确房间隔缺损的解剖位置、观察封堵器释放后的形态结构、明确残余分流的性质及原因等方面较二维超声心动图具有明显优势。Objective： To evaluate the clinical value of real time three -dimensional echocardiography （RT -3DE） in atrial septal defect （ASD） before and after transcatheter closure. Methods： 187 patients with ASD were examined by RT- 3DE, and the size, position and shape of the defect were analyzed, then the position of the occluder and the distances from aortic value, mitral value and tricuspid value were examined by RT- 3DE after occlusion operation. Results： RT- 3DE could display the size, position, shape and the surrounding tis- sues of ASD and their occluders vividly. 25 patients had no atrial septal retained of inferior vena tara, distance of defect of 5 patients was o- ver 45 ram, and they had no atrial septal retained of atrial top and inferior vena cava, ASD of 1 patients was cribriform and surgery was car- ried out. Conclusion： RT -3DE has more advantages than 21） - echocardiography in examining the anatomical position of ASD, observing the shape and structures of oecluders after operation and identifying the characters and reasons of remaining blood shunt.
