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. Conclusion. 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.展开更多

The results showed that BTEE was not influenced by corpulent and pulmonary emphysema and was better than transthoracic echocardiography at imaging the interatrial septum, left atrium and left atrial appendage, thoracic aorta, and mitral artificial valve and at intraoperative monitoring. BTEE was also better than single-plane transesophageal echocardiography,because BTEE could be used to observe the heart and thoracic aorta in transverse and longitudinal planes, thus enlarging the transmission 'window' as well as allowing the entire lesion to be imaged.This study suggests that BTEE will have good prospects in clinical application.展开更多
