摘　　要：目的:探讨经胸超声心动图(TTE)在引导Amplatzer封堵器经心导管封堵继发孔中央型房间隔缺损(ASD)治疗术前、术中、术后的临床应用价值。方法:运用TTE筛选出适于封堵术的继发孔型ASD患者89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引导封堵术成功率100%。术后封堵完全闭合率93.3%(83/89),一周后为95.5%(85/89),3个月以上为100%。术后随访均未发现封堵器结构断裂、移位、血栓形成等并发症发生。结论:运用TTE引导Amplatzer封堵器经心导管封堵ASD是否成功,术前病例的筛选及封堵器型号的选择是关键,而且TTE较经食道超声操作简便、安全,更易掌握及推广。此外,对术后疗效评价有重要临床价值。Objective：To investigate the clinical application of transthoracic echocardiography（TTE）in the process of operation for occlusion of secundum atrial septal defect by guiding Amplatzer occluder to cardiac catheter.Methods：89 patients who may benefit from surgery treatment for occlusion of secundum atrial septal defect were screened by TTE.The closure procedure was guided by Xray,and the septal occluders with suitable size were selected and followed up for patients.Results：The success rate for operation was 100% using Amplatzer occluder under TTE guidance.Complete closure rate was 93.3%（83/89）after operation,95.5%（83/89）in a week,and 100% more than three months.The complications,such as the rupture or transportation of ASD and thrombosis,were not observed in follow-up studies.Conclusions：Both primarily screening of cases and the selection of ASD with suitable size play key roles for successful application of Amplatzer occluder under TTE guidance for the operation treatment of secundum atrial septal defect.Furthermore,TTE is safer and easer to operation than transesophageal echocardiography（TEE）,and has important clinical value for post-operative evaluation.
