目的 探讨经食管超声心动图 (TEE)在房间隔缺损 (ASD)及伴心内其他疾患介入治疗中的应用价值。方法 采用 TEE准确评价 ASD的空间方位、大小和边缘状况 ,及其与周围心内结构的关系 ,并在 TEE引导下对单纯性 ASD、L utembacher综合征 ,Triology of Fallot三联症 (TOF3)、部分适合封堵的房间隔膨胀瘤并ASD、多发性 ASD进行综合性介入治疗。结果 31例中 ,30例用 Amplatzer封堵器对 ASD封堵成功。对伴发的二尖瓣狭窄、肺动脉瓣狭窄于 ASD封堵前行瓣膜球囊扩张术 ;对多发性筛孔状 ASD先行球囊房间隔造口术 ,然后选用匹配的封堵器封堵 ,无残余分流。 1例封堵失败 ,为 ASD伴永存左上腔静脉引流入重度扩张的冠状静脉窦。结论 TEE对于术前病例筛选 ,术中引导心导管、球囊和封堵器送入、定位和释放具有重要作用
Objective To investigate the value of transesophageal echocardiography (TEE) in the interventional treatment of atrial septal defect (ASD) and other disorders with heart disease. Methods TEE was used to evaluate the spatial location, size and marginal status of ASD and its relationship with the surrounding cardiac structure. The TEE was used to evaluate the association of simple ASD, Lutembacher syndrome, Triology of Fallot triad (TOF3) Suitable for closure of the room by the expansion of aneurysm and ASD, multiple ASD for comprehensive intervention. Results Of the 31 cases, 30 cases were successfully blocked with Amplatzer occluder. For the associated mitral stenosis, pulmonary stenosis in the ASD occlusion before the valve balloon dilatation; multiple mesh-like ASD first balloon atrial septostomy, and then use the matching occluder block, No residual diversion. One patient failed the ASD with perpetuated left superior vena cava into the severely dilated coronary sinus. Conclusions TEE plays an important role in the screening of preoperative cases, intraoperative guiding of cardiac catheter, balloon and occluder in, positioning and release
