摘要 目的:探讨组织多普勒(TDI)Tei指数评价法洛四联征(TOF)患者右室功能的价值。方法:应用TDI获取31例TOF患者手术前、术后12天和3个月心脏三尖瓣环侧壁处的运动频谱,测量运动速度及时间间期(a’)及间期(b’),计算TDI-Tei指数,并与传统多普勒频谱法测得的Tei指数(C-Tei)比较,观察TOF患者手术前后右室功能的变化。结果:TOF患者术后12天、3个月右室TDI-Tei指数较术前明显增大(P<0.01),C-Tei指数较术前明显减小(P<0.05);术后12天、3月TDI测得的三尖瓣环运动速度值较术前明显减小(P<0.05)。结论:TDI技术用于测量TOF患者术后右室Tei指数较传统方法更为敏感,准确;TOF患者术后早期右室整体功能减低。
