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 value of real-time three-dimensional echocardiography (RT-3DE) before and after atrial septal defect occlusion. Methods: 187 patients with atrial septal defect were detected by RT-3DE. The position, size and shape of the defect were analyzed. RT-3DE was used to evaluate the occluder position and the distance from the aortic valve, mitral valve and tris Cusps and other tissues and blood vessels around the distance. Results: RT-3DE can display the relationship between atrial septal defect and its location, shape and its surrounding tissue in real time and dynamically. There were no stump echo in the inferior vena cava of 25 cases, and the largest of 5 cases 45 mm above the pitch, and the atrial appendage atrial appendage and inferior vena cava showed no obvious residual echo, a case of defect because of the mesh-like rerouting surgery. CONCLUSION: RT-3DE has obvious advantages over two-dimensional echocardiography in determining the anatomical location of atrial septal defect, observing the morphological structure of the occluder after release, and clarifying the nature and causes of residual shunt.
