The alteration of the pulmonary artery flow spectrum with pulmonary hypertension.
OBJECTIVE
To research the alteration of pulmonary flow spectrum of patients with congenital heart disease and the relation between pulmonary flow spectrum and pulmonary artery pressure, 33 patients with congenital heart disease were examined by echocardiography and catheterization.


RESULTS
The result showed that the spectrum peak early occurring in patients with pulmonary hypertension and the degree of the spectrum peak early occurring was related to pulmonary artery pressure positively. The result suggested that when the pulmonary artery systolic pressure was over 100 mmHg, the flow spectrum showed slender pattern usually.


CONCLUSIONS
The slender pattern in pulmonary flow spectrum could be a semi-quantity parameter to predict that the pulmonary artery systolic pressure more than 100 mmHg.
