Abstract:
The pressure and resistance of the pulmonary artery are the most important factors when evaluating the congenital heart disease. They are easily measured by the cardiac catheterization, but this procedure is a invasive technique, and difficult to perform repeatedly. There were some reports to estimate the pulmory artery pressure by using non-invasive techniques, such as the echocardiography. The accuracy and the application of the estimate derived from this technique is still a matter of controversy. We estimate the right ventricular pressure by the real time two dimensional echocardiography. The way to measure accuracy for this technique is by of camparing the estimate the right ventricular pressure derived by the echocardiograpy against the right ventricular pressure measured by the cardiac catheterization. The diameter of the left ventricle in the plane of the papillary muscles in measured by short axis view from parasternal positions at the end-systolic phase. The diameter between the interventricular sulcus[B] and the longest vertical from to the interventricular septum[C] are measured. The relationship between the ration, C/B by the two-dimensional echocardiography and the RVP/LVP by the cardiac catheterization is relatively well correlated(r=-0.88). Thus we may conclude that measuring the right ventricular pressure by using the two-dimensional echocardiography is relatively accurate and should be used for evaluating the congenital heart disease.
