Persistent truncus arteriosus (PTA) is a relatively uncommon congenital heart disease, accounting for approximately 0.7-1.4% of all congenital cardiac abnormalities worldwide. PTA is usually accompanied by a single semilunar valve, with leaflets ranging from one to six in number. However, absent semilunar valve (ASV) is rarely seen in PTA. Here, we report a case of prenatally diagnosed PTA accompanied by ASV (PTA-ASV) confirmed by postmortem autopsy.
永存动脉干（PTA）是一种相对罕见的先天性心脏病，约占全球所有先天性心脏异常的0.7-1.4%。PTA通常伴有单个半月瓣，瓣叶数量从1到6个不等。然而，永存动脉干中半月瓣缺如（ASV）的情况很少见。在此，我们报告一例经产前诊断为永存动脉干并伴有半月瓣缺如（PTA-ASV）的病例，该病例经尸检证实。
