The purpose of the present study was to verify the value of a two-dimensional pulsed Doppler echocardiographic method for measurement of pulmonary (QP) and systemic blood flow (QS) in comparison with the radiocardiography in patients with ventricular and atrial septal defects. We reviewed 42 children with ventricular septal defect and 23 children with atrial septal defect. Two-dimensional echocardiography was employed to measure the diameter of the aorta and pulmonary artery and pulsed Doppler for measurement of pulmonary and systemic blood flow velocity in the pulmonary artery and left ventricular outflow tract. By comparing pulmonary and systemic blood flow ratios by pulsed Doppler echocardiography and radiocardiography, the correlation coefficient for children with atrial septal defect and those with ventricular septal defect respectively amounted to r = 0.71 and r = 0.81. The authors conclude that two-dimensional pulsed Doppler echocardiography, although a semiquantitative technique, appears to be a reliable non-invasive method for measuring pulmonary and systemic blood flow in patients with left-to-right sgunt.
本研究的目的是验证二维脉冲多普勒超声心动图测量室间隔和房间隔缺损患者肺血流量（QP）和体循环血流量（QS）的价值，并与放射性心动造影术进行比较。我们回顾了42例室间隔缺损患儿和23例房间隔缺损患儿。采用二维超声心动图测量主动脉和肺动脉直径，用脉冲多普勒测量肺动脉和左心室流出道的肺血流量和体循环血流速度。通过比较脉冲多普勒超声心动图和放射性心动造影术测得的肺血流量与体循环血流量比值，房间隔缺损患儿和室间隔缺损患儿的相关系数分别为r = 0.71和r = 0.81。作者得出结论，二维脉冲多普勒超声心动图虽然是一种半定量技术，但似乎是一种可靠的非侵入性方法，可用于测量左向右分流患者的肺血流量和体循环血流量。
