摘要
经导管房间隔缺损介入封堵术(TCASD)在治疗房间隔缺损(ASD)中已具有较高的成功率,筛选适应证和准确安置封堵器对手术成功至关重要。新近研发的实时三维经食管超声心动图(RT3D-TEE)技术可获取高质量的三维图像,并可直视缺损,精确测量缺损内径和面积,更好地评价缺损残缘及与周围结构的关系;实时、全程监护TCASD,纠正封堵器植入处残余分流、降低术后并发症。RT3D-TEE是评价ASD及指导介入治疗的新选择、新参考。本文对RT3D-TEE在诊断及介入治疗ASD中的应用进展进行综述。
Transcatheter closure of atrial septal defects（TCASD）has excellent success rate for treatment of ASD.Appropriate selection of patients and suitable device implantation remain crucial for the procedure＇s success.Real-time three-dimensional transesophageal echocardiography（RT3D-TEE）is a recently developed technique that allows acquisition of high-quality RT3D images.Using RT3D-TEE,a defect of the interatrial septum（IAS）can be visualized enface.The accurate measurements of defect size and area,better estimation of the rim,as well as the spatial relationship between the ASD and cardiac structure can be easily demonstrated.RT3D-TEE allows continuous visualization of the procedure of TCASD,verification of the absence of flow across the device minimizing the complications.RT3D-TEE is a powerful new imaging tool that may become the technique of choice and the standard of evaluation of ASD morphology and for interventional guidance.The application progresses of diagnosis and interventional treatment of ASD using RT3D-TEE were reviewed in this article.
