摘　　要：目的:分析经胸超声心动图(TTE)带软边测量房间隔缺损(ASD)大小及指导封堵器型号选择的准确性。方法:ASD患者516例术前行TTE检查,采用带软边测量法和常规测量法分别多切面测量ASD直径,分别与封堵器型号作相关性分析,并将两组直径与封堵器型号作比较。结果:TTE带软边测量ASD最大径与封堵器型号相关性优于常规测量(r分别为0.92、0.90,均P<0.01)。两组ASD直径与封堵器型号比较差异均有统计学意义(均P<0.01),但带软边测量ASD直径与封堵器型号差值较小。结论:TTE带软边测量ASD大小较常规测量更精确,预判封堵器型号更准确。Objective：To analyze the accuracy of transthoracic echocardiography with soft-rim measurement to evaluate atrial septal defect（ASD）size and predict the size of ASD occluder.Method：A total of 526 ASD patients who underwent closure were involved in the study.The ASD maximal diameter was measured by transthoracic echocardiography（TTE）with soft-rim and without soft-rim before the transcatheter closure.Then the correlation between measured diameter and occluder size was analyzed.Filally,the two ASD maximal diameters measured by different methods were compared with occluder size respectively.Result：There was a better correlation between the size of occluder and the ASD size with soft-rim than without soft-rim measured by TTE（r=0.92 and 0.90,both P〈0.01）.There was a significant difference between the size of occluder and the ASD diameters in the two methods,but the first difference was smaller.Conclusion：Transthoracic echocardiography with soft-rim measurement method is more accurate than conventional method to measure the size of ASD,and it can accurately predict the size of the occluder.
