Prenatal diagnosis of a patient with tetralogy of fallot and an absent pulmonary valve

Abstract

A 34-week-gestation fetus of a gravid 3 mother 29 years of age was referred to our hospital due to an abnormal vascular image on obstetric ultrasonographic examination. The family history of congenital heart disease was negative. The mother had been using valproate due to epilepsy. Fetal echocardiography showed aneurysm of the pulmonary artery and rudimentary pulmonary valve and pulmonary regurgitation (Figs. 1, 2, movie 1). Tetralogy of Fallot and an absent pulmonary valve was diagnosed (Figs. 3, 4, 5).
