Abstract

In order to evaluate the effecacy of 2D-Doppler echocardiography for the measurement of pulmonary flow(Qp), systolic flow(Qs), the ratio of pulmonary flow and systemic flow and systemic flow(Qp/Qs), 19 membranous ventricular septal defect patients were examined in the period from July, 1986 to October, 1987 at Ewha Women's university hospital. The measurement of Qp, Qs, Qp/Qs by 2D-Doppler echocardiography were compared with the results by the Fick's method of cardiac catheterization.The following results were obtained. 1) The total of the 19 patients consisted of 15 males and 4 females. The mean age of the patients was 8.2 years. 2) It was found that the Fick's method and 2D-Doppler measurements of Qp (n=19, r=0.67), Qs (n=19, r=0.88), and Qp/Qs ratio(n=19, r=0.62) were highly correlated(p<0.01). 3) It is understood that the measurement of Qp, Qs, Qp/Qs ratio by 2D-Doppler echocardiography were quite useful to the noninvative diagnosis of ventricular septal defect.
