Application Value of Real-time Three-dimensional Echocardiography(RT-3DE)and MRI in Evaluating Cardiac Function of Patients with Tetralogy of Fallot(TOF)

目的观察实时三维心脏超声(RT-3DE)与磁共振成像(MRI)在评估法洛四联症(TOF)患者心功能中的应用价值。方法选取我院收治的25例行一期根治术TOF患者,采取RT-3DE与MRI方式了解患者心功能指标情况[左室与右室舒张末期容量(LVEDV与RVEDV)、左室与右室收缩末期容量(LVESV与RVESV)、左室与右室射血分数(LVEF与RVEF)],并分析这两种检查方式所得心功能指标相关性。结果RT-3DE与MRI检查出的LVEDV、RVEDV、LVESV、RVESV、LVEF及RVEF比较无显著差异(P>0.05);RT-3DE与MRI检查出的LVEDV、RVEDV、LVESV、RVESV、LVEF以及RVEF具有良好一致性(P<0.05)。结论RT-3DE评估TOF患者心功能与MRI评估结果一致性好,在TOF心室功能检测中具有较高应用价值。

Objective To investigate the application value of real-time three-dimensional echocardiography(RT-3DE)and MRI in evaluating cardiac function of patients with tetralogy of Fallot(TOF).Methods 25 patients with TOF undergoing stage one radical resection who were admitted to the hospital were enrolled.RT-3DE and MRI were performed to understand cardiac function[left and right ventricular end-diastolic volume(LVEDV and RVEDV),left and right ventricular end systolic volume(LVESV and RVESV),left and right ventricular ejection fraction(LVEF and RVEF)].The correlation of cardiac function indexes measured by the two methods was analyze.Results There was no significant difference in LVEDV,RVEDV,LVESV,RVESV,LVEF or RVEF examined by RT-3DE and MRI(P>0.05).The consistencies of LVEDV,RVEDV,LVESV,RVESV,LVEF and RVEF were god detected by RT-3DE and MRI(P<0.05).Conclusion The consistencies of RT-3DE and MRI are good for assessing cardiac function of TOF patients,which are of relatively higher application value in TOF ventricular function testing.
