目的探讨经食道超声心动图(TEE)筛选评价介入封堵继发孔型房间隔缺损(ASD)的可行性。方法33例确诊的ASD患者,术前行经食管超声心动图(TEE)检查,测量缺损大小、形态、位置及周边结构,所有病例均采用Amplatzer封堵器封堵。结果31例封堵成功,TEE测量ASD最大径32mm,最小径5mm(16.3±5.8),选用封堵器大小10~36mm(20.9±6.1),二者呈直线相关(r=0.95),2例失败。对ASD边缘较软、较薄、摆动或飘动者,设为无效边缘,所测缺损孔直径更接近封堵器直径。结论TEE是可对拟行封堵治疗继发孔型房间隔缺损患者术前筛选,值得推广。
Objective To evaluate the feasibility of transesophageal echocardiography (TEE) screening for the treatment of secondary atrial septal defect (ASD). Methods Totally 33 ASD patients diagnosed as ASD were examined by transesophageal echocardiography (TEE) preoperatively to measure the size, shape, location and perimeter of the defect. All cases were occluded with Amplatzer occluder. Results 31 cases were successfully blocked by TEE. The maximum diameter of ASD measured by TEE was 32 mm and the minimum diameter was 5mm (16.3 ± 5.8). The size of occluder was 10 ~ 36 mm (20.9 ± 6.1). There was a linear correlation between them (r = 0.95) failure. For ASD edge soft, thin, swing or flutter, as the invalid edge, the diameter of the measured defect hole closer to the occluder diameter. Conclusion TEE is a preoperative screen for the treatment of patients with atrial septal defect secondary to occlusion and is worth promoting.
