目的　探讨组织多普勒（TDI）Tei指数评价房间隔缺损（ASD）无并发肺动脉高压患者右室功能的改变。方法　选取2012年3月－10月无并发肺动脉高压的继发孔型房间隔缺损患者31例（ASD组）及健康体检者30例（对照组），应用TDI成像获取三尖瓣环运动频谱，测定频谱图上Aa 峰至S峰的时间（等容收缩时间，ICT），S峰的持续时间（射血时间，ET）和S峰至Ea峰的时间（等容舒张时间，IRT），计算右室Tei指数。房缺组Tei指数及相关参数与缺损大小和患者年龄作相关性研究。结果　ASD损无并发肺动脉高压患者右室等容收缩时间（ICT）低于正常对照[（45 ± 7）、（59 ± 8）ms，P＜0.001]，右室等容舒张时间（IRT）高于正常对照[（85 ± 5）、（78 ± 14）ms，P＜0.01]，房缺组Tei指数低于正常对照（0.48 ± 0.03、0.52 ± 0.05，P＜0.001）。房缺组的缺损大小与Tei指数、ICT呈负相关（r=?0.61，P＜0.01；r=?0.44，P＜0.05），而患者年龄与Tei指数、ICT及IRT呈正相关（r=0.69，P＜0.001；r=0.75，P＜0.001；r=0.63，P＜0.001）。结论　TDI Tei指数是无创、有效和快捷评价右室功能的方法；ASD无并发肺动脉高压患者的ICT缩短，Tei指数减低，右室收缩和整体功能增强，而IRT延长，舒张功能受损；缺损越大，右室收缩和整体功能越强；年龄越大，右室整体功能相对减低。
