Persistent truncus arteriosus with absent semilunar valve in first trimester

AbstractPersistent 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.
