"Absence" of the pulmonary valve was recognized by cross-sectional echocardiography in two infants having relatively atypical clinical manifestations for this cardiac malformation. Both had associated lesions: tetralogy of Fallot and ventricular septal defect, respectively, which were also detected by this non-invasive technique. The findings which strongly suggested the diagnosis were the presence of a ridge of rudimentary pulmonary valvular tissue at the level of the pulmonary annulus and the aneurysmal dilation of the pulmonary arteries. The short axis view at the level of the great arteries was the best approach for visualization of these anatomical abnormalities. The parasternal long axis and sub-costal four-chamber views were also helpful in detecting the associated lesions. In both cases the diagnoses were confirmed at autopsy.
两名患有这种心脏畸形但临床表现相对不典型的婴儿，通过超声心动图断层扫描发现肺动脉瓣“缺如”。两人分别伴有法洛四联症和室间隔缺损等相关病变，这些病变也通过这种非侵入性技术检测到。强烈提示诊断的发现是在肺动脉瓣环水平存在一条发育不全的肺动脉瓣组织嵴以及肺动脉瘤样扩张。大动脉水平的短轴视图是观察这些解剖异常的最佳方法。胸骨旁长轴和肋下四腔视图也有助于检测相关病变。在这两个病例中，尸检均证实了诊断。
