Structural and hemodynamic study of right ventricular outflow tract reconstruction with valved bovine jugular vein conduit in pulmonary atresia by color Doppler echocardiography;

Objectives To analyze the anatomy and morphology of the pulmonary circulation of pulmonary atresia with ventricular septal defect(PA/VSD)and to study the eligible surgical approach.

Objective In order to provide pathologic reference for therapeutic rationale, the pathological changes of the pulmonary vasculature in patients with pulmonary atresia with ventricular defect and patent ductus arteriosus were observed by contrast with normal control group.

Application of percutaneous transluminal angioplasty and stenting in patients with subclavian artery occlusion;
