Objective To evaluate the ability of transthoracic Doppler echocardiography in assessing atrial secundum septal defect before and post-operation.Methods Retrospective reviewed cased from January 2010 to January 2013 who ad-mitted with secundum atrial septal defect and successfully received implemented interventional surgery ( n =20 ) .Analyzed the relationship between preoperative transthoracic echocardiography measured the maximum diameter of the defect and the catheter based measurement of the balloon occluder model .Transthoracic Doppler echocardiography were applied at 3 d after operation and three months after operation , to review the position and shape of the occluder , the size and function of the right atrium and right ventricle , as well as changes in the pulmonary artery .Results Preoperative atrial septal defect size measured by transthoracic echocardiography was 7-40 (24.6 ±8.2) mm, intraoperative determination the size and then success release of the balloon occluder , the measured value was 8-40 (24.8 ±8.5) mm, Spearman correlation analysis showed that there was a significant correlation between the two measurement ( r =0.930, P <0.01).After 3 d and 3 months of operation, transthoracic color Doppler echocardiography examination showed normal morphology and position of occluder , the right atrium diameter and anterior to posterior diameter of the right ventricle , pulmonary artery diameter , right ventricular end-diastolic vol-ume (RVEDV), right ventricular end-systolic volume ( RVESV), right ventricular stroke volume ( RVSV) were improved significantly compared with the before operation , and the difference was statistically significant ( P <0.01).Compared with the before operation , 3 d and 3 months after operation , right atrial diameter from top to bottom , anterior to posterior diameter of right ventricular , pulmonary artery diameter , right ventricular systolic diameter , right ventricular end-diastolic diameter and right ventricular stroke volume was significantly reduced ( P <0.01), after three months improved more significantly ( P <0.05).Conclusion Transthoracic Doppler echocardiography is safe , effective and easy way to guide and evaluate secundum atrial septal defect occlusion .%目的：评价经胸彩色多普勒超声心动图在继发孔型房间隔缺损患者行介入封堵术前评估以及术后随访中的应用价值。方法采用回顾性研究的方法，收集2010年1月-2013年1月收治的继发孔型房间隔缺损成功实行介入封堵术的患者20例。分析术前经胸超声心动图测量的缺损最大径与术中球囊测量并成功应用的封堵器型号的关系。于术后3d及3个月进行经胸彩色多普勒超声心动图复查，了解封堵器的位置和形态，右心房、右心室的大小与功能以及肺动脉内径变化情况。结果术前房间隔缺损经胸超声心动图测量值为7～40（24．6±8．2）mm，术中经球囊测定后成功释放不同规格的封堵器，测量值为8～40（24．8±8．5）mm，Spearman相关性分析表明两者之间有显著相关性（ r ＝0．930， P ＜0．01）。术后3 d及3个月经胸彩色多普勒超声心动图检查显示封堵器位置与形态正常，右心房上下径、右心室前后径、肺动脉内径、右室舒张末期容积（RVEDV）、右室收缩末期容积（RVESV）、右室每搏输出量（ RVSV）均较术前有明显改善，差异有统计学意义（ P ＜0．01）。与术前比较，患者术后3 d及术后3个月右心房上下径、右心室前后径、肺动脉内径、RVEDV、RVESV及RVSV均显著缩小（ P ＜0．01），且与术后3 d比较，术后3个月改善更明显（ P ＜0．05）。结论经胸彩色多普勒超声心动图是指导与评价继发孔型房间隔缺损介入封堵术安全、有效、简便的方法。
