This would suggest pulmonaryatresia with a ventricular septal defect, and the flow is blood going to the lungs only.

Objectives To analyze the anatomy and morphology of the pulmonary circulation of pulmonaryatresia with ventricular septal defect(PA/VSD)and to study the eligible surgical approach.
目的研究肺动脉闭锁合并室间隔缺损的解剖类型和血流动力学改变，并探讨其适宜的手术方式。
