【摘要】：目的应用实时三维超声心动图(RT-3DE)评价法乐氏四联症(TOF)患儿右室整体及局部容积和收缩功能。方法 RT-3DE采集45例TOF患儿,平均年龄(1.37±2.91)岁及46例正常同龄匹配对照组,平均年龄(1.37±2.85)岁右室全容积声像图,应用TomTec RV-Function软件分析右室整体及局部容积和收缩功能,测量指标:舒张末期容积(EDV)、收缩末期容积(ESV)、射血分数(EF)、容积峰值收缩速率(PSVR)。结果右室整体、流入道、心尖小梁部EDV与正常对照组无显著差异(P0.05),但上述各容积值为体表面积标化后均大于正常对照组(P0.05),流出道EDV及标化后容积均较正常对照组减小(P0.05);右室整体EF、PSVR及三局部EF均较正常对照组减低(P0.05)。结论 TOF患儿右室流出道发育不良性狭窄导致右室流出道容积减小,而右室整体、流入道、心尖小梁部容积增大,并伴有右室收缩功能受损。
[Abstract]:Objective to evaluate TOF in tetralogy of Fallot by real-time three-dimensional echocardiography (RT-3DE). Methods 45 cases of TOF were collected by RT-3DE. The mean age was 1.37 卤2.91) years old and 46 normal matched controls. The mean age was 1.37 卤2.85 years old. The whole and local volume and systolic function of right ventricle were analyzed by TomTec RV-Function software. Results there was no significant difference in EDV between the right ventricular mass, inflow tract and apical trabeculae between the two groups (P 0.05). However, the volume values of each volume were larger than that of the normal control group after the surface area was standardized, and the outflow tract EDV and the standardized volume were decreased compared with the normal control group. The PSVR and EF in the whole right ventricle were lower than those in the control group (P 0.05). Conclusion the volume of right ventricular outflow tract decreases in children with TOF due to dysplasia of right ventricular outflow tract. On the other hand, the volume of the apex trabeculae and the right ventricular systolic function were increased in the whole right ventricle, the inflow tract and the apical trabeculae.
