| Abstract |
|
This study determined the accuracy of Doppler echocardiography for predicting the pulmonary
artery pressure from right ventricular systolic time intervals in 25 pediatric patients with various
congenital cardiovascular diseases undergoing cardiac catheterization.
Either estimated pulmonary artery systolic pressure (PASP) using Burstin nomogram and pulmo-
nary artery diastolic pressure (PADP) using Riggs equation (PADP= 151· RPEP / RVET ·20.7) correlated
well with the pressures at cardiac catheterization. The coπelation coefficient were 0.88 and 0.94
respectively.
The use of this technique permitted the noninvasive estimation of the pulmonary artery pressure. |
