The absence of the pulmonary valve and the left pulmonary artery were recognized by cross-sectional and Doppler echocardiography in one patient with tetralogy of Fallot. The right oblique subxiphoid view was the best approach for visualization of these anatomical abnormalities. The diagnosis was confirmed at catheterization and at operation. It is suggested that premature closure of the ductus arteriosus may be responsible for the failure in the development of both the pulmonary valve and the left pulmonary artery.
在一名法洛四联症患者中，通过横断面和多普勒超声心动图发现肺动脉瓣和左肺动脉缺如。剑突下右斜位视图是观察这些解剖异常的最佳途径。心导管检查和手术证实了诊断。提示动脉导管过早闭合可能是肺动脉瓣和左肺动脉发育不良的原因。
