Absent pulmonary valve syndrome with tetralogy of Fallot detected at an early gestational age of 27 weeks – A case report

摘要

ObjectiveAbsent pulmonary valve syndrome (APVS) is a rare congenital anomaly, usually seen in association with a ventricular septal defect. It has been reported to occur in 3–6% of cases of tetralogy of Fallot (TOF). In this case report we discuss a case of absent pulmonary valve syndrome with tetralogy of Fallot that was detected in utero by fetal echocardiography at 27 weeks of gestation.
