摘　　要：目的:评价Tei指数估测儿童三尖瓣下移畸形手术前后心功能变化的价值。方法:38例接受三尖瓣下移畸形手术治疗的患儿,分别于手术前后应用超声心动图测量左、右心室Tei指数。另选取80名正常儿童作为对照组。结果:正常组左、右心室Tei指数分别为0.30±0.08、0.26±0.08,三尖瓣下移畸形患儿术前左、右心室Tei指数分别为0.46±0.09、0.50±0.11,均高于正常组(P<0.05),术后患者左、右心室Tei指数分别为0.36±0.06、0.33±0.06,明显降低,但尚未恢复至正常组水平(P<0.05)。结论:三尖瓣下移畸形患者术前存在心功能不全,手术可以得到改善;Tei指数可以较准确评价三尖瓣下移畸形患者的心功能变化。Objective:To investigate the clinical value of Tei index in evaluating cardiac function in children with Ebstein anomaly before and after operation.Methods:Ebstein group included 38 children.Doppler Tei index of the left and the right ventricles was obtained before and after operation.Control group included 80 healthy children.Tei index of the left and the right ventricle was calculated to obtain the normal reference value.Results:The normal value of LV Tei index was 0.30±0.08,RV Tei index was 0.26±0.08.In the Ebstein group,both RV and LV Tei index were abnormally increased compared with normal subjects before operation(Ebstein group: RV Tei =0.50±0.11,LV Tei = 0.46±0.09,P<0.05).Then gradually recovered after operation,but Tei index had not recovered completely compared with control group(P<0.05).Conclusion:Tei index could be applied to assess cardiac function in children with Ebstein anomaly before and after operation.
