Absent pulmonary valve syndrome (APVS) is a rare congenital heart defect, usually associated with tetralogy of Fallot (TOF), although other associations have been described. A pregnant woman was referred to fetal echocardiography clinic from the Maternal Fetal Medicine department due to abnormal findings on routine antenatal ultrasound, showing a pulsatile cystic mass above the left atrium and a suspected TOF. A fetal echocardiogram confirmed the presence of TOF/APVS. The pulsatile cystic mass was the aneurysmally dilated main pulmonary artery. The exact origin of the left pulmonary artery (LPA) was not clearly established prenatally. A postnatal echocardiogram of the neonate showed an abnormal origin of the LPA from the ascending aorta (hemitruncus). The neonate subsequently underwent surgical repair with a good outcome. We present a novel case of a TOF/APVS associated with an abnormal origin of the LPA from the ascending aorta.
肺动脉瓣缺如综合征(APVS)是一种罕见的先天性心脏缺陷,通常与法洛四联症(TOF)相关,不过也有其他相关联的情况被描述过。一名孕妇因常规产前超声检查发现异常,从母胎医学科转诊至胎儿超声心动图诊所,超声显示左心房上方有一个搏动性囊性肿块,疑似法洛四联症。胎儿超声心动图证实存在法洛四联症/肺动脉瓣缺如综合征。搏动性囊性肿块是呈瘤样扩张的主肺动脉。产前未明确左肺动脉(LPA)的确切起源。新生儿出生后的超声心动图显示左肺动脉起源于升主动脉(半干)异常。该新生儿随后接受了手术修复,效果良好。我们报告一例法洛四联症/肺动脉瓣缺如综合征合并左肺动脉起源于升主动脉异常的罕见病例。
