这种畸形即肺动脉和主动脉都由右室发出,左室的唯一出口就是室间隔缺损。临床表现有如伴有肺动脉高压的无合并症室间隔缺损。本病患者的主动脉是由右室发出的,而超声心动图可以发现二尖瓣前叶和主动脉间的不连续性,故可作出诊断。婴儿期间即常有难以控制的心衰和肺动脉高压,故常须对肺动脉进行束扎处理。 This deformity that the pulmonary artery and aorta are issued by the right ventricle, left ventricular outlet is the only ventricular septal defect. Clinical manifestations such as without complications associated with pulmonary hypertension ventricular septal defect. The patient’s aorta is issued by the right ventricle, and echocardiography can be found in the anterior mitral valve and the discontinuity between the aorta, it can make a diagnosis. During infancy, often with uncontrollable heart failure and pulmonary hypertension, it is often necessary to bundle the pulmonary artery.
