摘要： 摘要 目的：应用实时三维超声心动图（Real-time three-dimensional echocardiography,RT-3DE）评价左向右分流先天性心脏病继发肺动脉高压患者右室功能。方法：将74例左向右分流先天性心脏病患者分成轻度、中度、重度三 组，45例健康体检者作为正常对照组。分别用RT-3DE测量RVESV 、RVEDV、 RVEF。结果：与对照组相比较，中度、重度PAH患者RVEDV、RVESV增加，而RVEF值减低，差异具有统计学意义（P<0.05）。结论：RT-3DE可以准确评价左向右分流先天性心脏病继发肺动脉高压患者的右室功能。

Abstract: Abstract Objective：To evaluate left ventricular systolic function in patients with left-to-right shunting congenital heart disease associated different level pulmonary artery hypertension (PAH). Methods：74 patients with left-to-right shunting congenital heart disease and 45 age-matched healthy controls were involved. The patients were divided into mild, moderate and severesubgroups according to pulmonary artery pressure. To measured right ventricular end systolic volume (RVEDV)， right ventricular end diastolic volume （RVESV） and right ventricular ejection fraction (RVEF) by Real-time three-dimensional echocardiography(RT-3DE). Results：RVEDV,RVESV significantly increased in patients with moderate and severe PAH, and RVEF decreased obviously. Conclusions： RT-3DE can evaluate left ventricular function accurately.
