目的　探討組織多普勒（TDI）Tei指數評價房間隔缺損（ASD）無并發肺動脈高壓患者右室功能的改變。方法　選取2012年3月－10月無并發肺動脈高壓的繼發孔型房間隔缺損患者31例（ASD組）及健康體檢者30例（對照組），應用TDI成像獲取三尖瓣環運動頻譜，測定頻譜圖上Aa 峰至S峰的時間（等容收縮時間，ICT），S峰的持續時間（射血時間，ET）和S峰至Ea峰的時間（等容舒張時間，IRT），計算右室Tei指數。房缺組Tei指數及相關參數與缺損大小和患者年齡作相關性研究。結果　ASD損無并發肺動脈高壓患者右室等容收縮時間（ICT）低于正常對照[（45 ± 7）、（59 ± 8）ms，P＜0.001]，右室等容舒張時間（IRT）高于正常對照[（85 ± 5）、（78 ± 14）ms，P＜0.01]，房缺組Tei指數低于正常對照（0.48 ± 0.03、0.52 ± 0.05，P＜0.001）。房缺組的缺損大小與Tei指數、ICT呈負相關（r=?0.61，P＜0.01；r=?0.44，P＜0.05），而患者年齡與Tei指數、ICT及IRT呈正相關（r=0.69，P＜0.001；r=0.75，P＜0.001；r=0.63，P＜0.001）。結論　TDI Tei指數是無創、有效和快捷評價右室功能的方法；ASD無并發肺動脈高壓患者的ICT縮短，Tei指數減低，右室收縮和整體功能增強，而IRT延長，舒張功能受損；缺損越大，右室收縮和整體功能越強；年齡越大，右室整體功能相對減低。
