Chest X-ray showed an enlarged right ventricle. Echocardiography demonstrated characteristic features of Fallot＇s tetralogy and the left pulmonary artery could not be visualized. However, cardiac catheterization disclosed that the left pulmonary artery had an anomalous origin in the ascending aorta. The patient underwent total surgical correction of the defects. Nine days later, he was discharged. We present the results of a literature review of the incidence, physiopathological, clinical, diagnostic, and surgical characteristics of this rare disease.展开更多

The further studies show the negative relation is more significant in the state-owned listed companies,which proved our speculation that the manager will cut expenses avoiding significant decline in performance when the sales decline in the state-owned listed company.展开更多
