This study determines the accuracy of Doppler echocardiography for predicting the presence of
pulmonary artery hypertension from Doppler pulmonary artery velocity traces.
The patient group included 26 patients with congenital cardiac disease who had undergone
catheterization.
Doppler measurements of acceleration time(AT), right ventricular ejection time (RVET), and AT/
RVET were compared with pulmonary artery pressure (PAP) and mean pulmonary artery pressure
(m-PAP).
We devided the patients in... |
