Sometimes the pulmonary valve is completely obstructed (pulmonary atresia).
有时候肺动脉瓣完全阻塞(肺动脉瓣闭锁)。
Conclusions Pulmonary atresia can be diagnosed accurately by echocardiography.
结论超声心动图可以确诊肺动脉闭锁。
This would suggest pulmonary atresia with a ventricular septal defect, and the flow is blood going to the lungs only.
提示肺动脉(瓣)闭锁合并室间隔缺损，血流仅流向肺脏。
