[Evaluation of the size of the left-right shunt using pulse Doppler echocardiography in children--personal experience].
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.
