摘要
目的预测法乐四联症（ＴＯＦ）根治术后低心排综合征（ＬＣＯＳ）的发生概率。方法应用多巴酚丁胺负荷三维超声心动图技术（３Ｄ－ＤＳＥ）检测ＴＯＦ根治术前左心室舒张末期容积（ＬＶＶｄ）、射血分数（ＬＶＥＦ）储备，患儿组２５例，男１４例，女１１例；对照组８例，男６例，女２例。结果ＴＯＦ根治术前ＬＶＶｄ减小、ＬＶＥＦ大致正常；３Ｄ－ＤＳＥ检测中ＬＶＶｄ、ＬＶＥＦ最大增高率明显减低；３Ｄ－ＤＳＥ试验阳性患儿根治术后ＬＣＯＳ发生率明显高于阴性患儿，其预测ＬＣＯＳ的敏感性为８８．８９％、特异性为７５．００％～８７．５０％、阳性预测值为６６．６７％～８０．００％、阴性预测值为９２．３１％～９３．３３％。
Objective\ To predict the low cardiac output syndrome (LCOS) following total correction of TOF. Methods\ Three dimensional dobutamine stress echocardiography (3D DSE) was employed to evaluate the left ventricular end diastolic volume(LVVd), ejectional fraction (LVEF) reserve before total correction of tetralogy of Fallot (TOF). 25 patients (male 14, female 11)and 8 normal controls (male 6, female 2) were examined in this study. Results\ It was showed diminished LVVd, poor LVEF reserve before total correction of TOF, and patients with positive 3D DSE testing results had more LCOS following total correction of TOF than those with negative ones. The sensitivity was 88.89%, specificity ranged was 75.00%￣87.50%, positive predictive value was 66.67%￣ 80.00 %, and negative predictive value was 92.31 %￣93.33%. Conclusions\ The DSE testing is important to predict the LCOS after total correction of TOF.
