摘　　要：目的探讨超声心动图在测定先天性室间隔缺损(VSD)合并肺动脉高压(PH)患者血流动力学参数的应用价值。方法 VSD合并不同程度PH患者80例,用超声心动图测量肺动脉瓣环内径(PAD)等参数,计算全肺阻力(TPR)、肺循环血流量(Qp)、体循环血流量(Qs)及肺/体循环血流量比值(Qp/Qs);3日内完成右心导管检查。比较二者检查结果。结果超声心动图和右心导管两种方法报告的TPR、肺动脉收缩压(PP)、肺动脉平均压(PAMP)和Qp/Qs高度相关。结论应用超声心动图能够准确测量VSD合并PH患者的血流动力学参数。Objective To study the value of echocardiography in the measurement of hemodynamics in patients with congenital ventricular septal defect（VSD） combined with pulmonary hypertension（PH）. Methods With echocardiography and right cardiac catheter examination, the hemodynamic criteria of pulmonary artery dimention （PVD）, total pulmonary resistance （TPR）, pulmonary circulatory volume （Qp）, systemic circulatory volume （Qs） and the ratio of Qp to Qs （Qp/Qs） were measured and calculated in 80 VSD patients with PH. The results reported by two methods were analyzed. Rsults The TPR, pulmonary systolic pressure, mean pulmonary artery pressure,and Qp/Qs reported by echocardiography were highly correlated to those reported by right cardiac catheterization. Conclusion The echocardiography can be used accurately to measure the hemodynamics in VSD patients with PH.
