| Abstract |
|
This study was desinged to assess the accuracy of the ratio of pulmonary to systemic blood flow (Qp/Qs) measured
by non-invasive continuous wave (CW) Doppler echocardiography comparing with other non-invasive Radionu-
clide Angiocardiography (RNA) and invasive Fick method.
Seventeen children with congenital heart disease, aged 14 months to 15 years, admitted for cardiac opention to this
hospital, were studied.
High correlations were found between the estimates of Qp/Qs (r=0.89, y=0.96x4-0.03, SEE=0.13) by Doppler and
Fick method.
With comparison between RNA and Fick method in nine patients, lower correlations (r=0.62, y=1.62x—0.42,
SEE=0.77) were found.
The results indicate that Qp/Qs ratio of the patients with congenital heart disease can be relatively accurately
measured by non-invasive CW Doppler echocardiography. |
