Tetralogy of Fallot with absent pulmonary valve is a rare congenital cardiac malformation detected in 3% to 6% of tetralogy of Fallot patients. The prognosis depends on respiratory complications. In the present case the diagnosis was made at 18 week's gestation with two-dimensional and Doppler echocardiography. A ventricular septal defect and overriding aorta, absent valve echo, pulmonary regurgitation, and cystic pulsatile dilatation of the left pulmonary artery were the main diagnostic criteria. Severe respiratory complications were assumed in combination with a hyperechogenic left lung and termination of pregnancy was performed at 20 weeks' of gestation.
法洛四联症合并肺动脉瓣缺如为一种罕见的先天性心脏畸形，在3%至6%的法洛四联症患者中可检测到。其预后取决于呼吸并发症。在本病例中，妊娠18周时通过二维和多普勒超声心动图做出诊断。室间隔缺损、主动脉骑跨、瓣膜回声缺失、肺动脉反流以及左肺动脉的囊性搏动性扩张是主要诊断标准。鉴于左肺回声增强，推测存在严重呼吸并发症，于是在妊娠20周时终止妊娠。
