At birth, three infants had typical to-and-fro murmurs and laboratory features suggesting tetralogy of Fallot with absent pulmonary valve. Initial posteroanterior chest x-ray films were atypical for the condition because of the apparent absence of dilation of the proximal pulmonary arterial tree. Lateral chest x-ray films invariably demonstrated a large hilar mass. Radiographic findings on the posteroanterior chest x-ray film considered pathognomonic for the complex lesion may not evolve until later during the first year of life.
出生时，三名婴儿有典型的来回杂音和实验室特征，提示法洛四联症合并肺动脉瓣缺如。最初的后前位胸部X光片对此病症并不典型，因为近端肺动脉树明显没有扩张。侧位胸部X光片总是显示有一个大的肺门肿块。后前位胸部X光片上被认为是该复杂病变特征性的影像学表现可能要到出生后第一年晚些时候才会出现。
