目的 探讨二维斑点追踪技术测定的三尖瓣环位移(TAD)评价右心室收缩功能的价值.方法 选择85例观察对象,其中RVEF＞50%的健康对照组40例,RVEF＜50%的右室收缩功能降低组45例.应用二维斑点追踪技术测定心尖四腔观三尖瓣环中点处(TADmid)的位移,实时三维超声心动图方法 获取右室射血分数(RVEF),并分析TADmid与RVEF的相关性.结果 右室收缩功能降低组TADmid[(8.01±3.93)mm]较健康对照组[(13.75±3.26)mm]显著减低,差异有统计学意义(t=7.28,P＜0.01).TADmid与RVEF呈正相关(r=0.76,P＜0.01),TADmid评价RVEF＞50%的截断点为9.7,敏感性为72%,特异性为86%.结论 二维斑点技术测定的TAD与RVEF相关性良好,且操作简便易行,有望成为临床评价右室收缩功能的新指标.

Objective To explore the value of tricuspid annular displacement (TAD) in evaluating right ventricular systolic function by speckle tracking imaging.Methods Forty healthy people (RVEF ＞50%) and forty five patients(RVEF ＜50%)were enrolled in this study.The apical four-chamber view was obtained and tricuspid annular midpoint displacement (TADmid) were measured by speckle tracking imaging.Right ventricular ejection fraction (RVEF) was measured by three-dimensional echocardiography.The correlation of tricuspid annular midpoint displacement (TADmid) and right ventricular ejection fraction (RVEF) was analyzed.Results These was statistical significance of tricuspid annular midpoint displacement between healthy people (RVEF ＞ 50%) and patients (RVEF ＜ 50%) (t = 7.28,P ＜ 0.01).There was positive correlation between TADmid and RVEF (P ＜ 0.01).The correlation coefficient between TADmid and RVEF was 0.76 (P ＜ 0.0l).The cut-off value of TADmid for RVEF ＞ 50% was 9.7 with a sensitivity of 72% and a specificity of 86%.Conclusions TAD by speckle tracking imaging showed an excellent correlation with RVEF.Tricuspid annular displacement by speckle tracking imaging was a simple and easy method,and it might be a new index in assessing right ventricular systolic function in clinical practice.
