| 目的 探讨三维斑点追踪成像（3D-STI）技术定量评价房间隔缺损（ASD）患者封堵前后左心室整体应变。方法 选取介入封堵成功的继发孔型ASD患者35例，分别于术前、术后2天和1、3、6个月接受常规超声心动图检查及3D-STI检查。常规超声心动图检查获取左心室舒张末期内径（LVEDD）、左心室收缩末期内径（LVEDS）、左心室舒张末期容积（LVEDV），左心室收缩末期容积（LVESV）、每搏量（SV）。采用3D-STI检查获取左心室整体纵向峰值应变（GPLS）、左心室整体圆周峰值应变（GPCS）、左心室整体径向峰值应变（GPRS）和左心室整体面积峰值应变（GPAS）。对术前与术后各时间点参数行统计学分析。结果 常规超声心动图检查示ASD患者术后各时间点LVEDD、LVEDS、LVEDV、LVESV、SV较术前增加（P均<0.05），但术后2天、1、3、6个月间两两比较，差异无统计学意义（P>0.05）。3D-STI检查结果示ASD患者术后各时间点左心室GPLS、GPCS、GPRS、GPAS较术前增加（P均< 0.05），且以术后2天增加最为明显，术后6个月GPLS、GPCS、GPAS较术后3个月增加（P均< 0.05）。结论 3D-STI技术可全面、准确地评价ASD患者封堵前后左心室心肌应变，较常规超声心动图可更客观、有效地评价术后左心室收缩功能变化。 |

| Objective To investigate the value of three-dimensional speckle tracking imaging (3D-STI) in quantitative evaluation of left ventricular global strain in patients with atrial septal defect (ASD) before and after transcatheter closure. Methods Totally 35 patients with secondary ASD who received successful transcatheter occlusion were selected. Routine echocardiography and 3D-STI examination were performed before the operation, 2 days, 1 month, 3 months and 6 months after the operation. Routine echocardiography was used to obtain the parameters of left ventricular end diastolic diameter (LVEDD), left ventricular end systolic diameter (LVEDS), left ventricular end diastolic volume (LVEDV), left ventricular end systolic volume (LVESV), stroke volume (SV) and other parameters. The left ventricular global peak longitudinal strain (GPLS), left ventricular global peak circumferential strain (GPCS), left ventricular global peak radial strain (GPRS) and left ventricular global peak area strain (GPAS) were examined with 3D-STI. The preoperative and postoperative parameters at each time point were analyzed statistically. Results Routine echocardiography showed that LVEDD, LVEDS, LVEDV, LVESV and SV increased significantly after operation, but no significant difference was found to compare each other 2 days, 1 month, 3 months and 6 months after operation (all P>0.05). 3D-STI examination showed that left ventricular GPLS, GPCS, GPRS and GPAS increased after operation, and the most increase was noticed at the second day after transcatheter occlusion. GPLS, GPCS and GPAS 6 months after operation were larger than those 3 months after operation (all P>0.05). Conclusion 3D-STI technique can evaluate the left ventricular global strain in patients with ASD before and after occlusion. Compared with conventional echocardiography, 3D-STI technique can objectively and effectively evaluate the changes of left ventricular systolic function. |
