经胸超声心动图引导下ASD封堵治疗的应用研究

Application Study of Transthoracic Echocardiography Guided on ASD Occlusion Therapy

目的：探讨经胸超声心动图（TTE）在引导心腔内封堵器经心导管封堵继发孔型房间隔缺损中的作用,并评价其初步疗效。方法：运用TTE选择出适于封堵术的继发孔型房间隔缺损（ASD）患者18例,并配合X线指导封堵过程,选择合适型号的封堵器并观察随访疗效。结果：TTE引导封堵技术成功率100%。术后封堵完全闭合率94.4%（17/18）,3个月以上为100%。TTE所测房缺的最大直径明显小于球囊伸展径（P〈0.01）,但二者高度相关（r=0.93）,为封堵器型号的选择提供了依据。本组18例术后随访,均未出现封堵器结构断裂、移位、血栓形成等并发症发生。结论：运用TTE引导心腔内封堵器经心导管封堵继发孔房间隔缺损是一种安全、有效的非外科手术方法,近中期疗效可靠。

Objective：To Explore the effect of transthoracic echocardiography（TTE）guided intracardiac occlusion on atrial septal defect（ASD）.Methods：18 cases were selected by TTE,and suitable diameter occluder was used in operation under the X-ray directed.Results：The success rate of TTE guided intracardiac occlusion was 100%.After the operation,the completed closure rate was 94.4%（17/18）and reached to 100% over three months of the operation.The diameter measured by TTE was markedly smaller than that of balloon extension（P0.01）,but there was significant correlation between them（r=0.93）,Therefore it could supply the reference for selecting the type of occluder.In this group of 18 cases,no case occurred complication of occluder break,translocation and thrombosis formation.Conclusion：Transthoracic echocardiography（TTE）guided on secondary atrial septal defect occlusion is a safe and effective non-operation therapy.
