Antenatal diagnosis of tetralogy of Fallot with absent pulmonary valve accompanied by hydrops fetalis and polyhydramnios.
The case presented is an antenatal diagnosis of tetralogy of Fallot with absent pulmonary valve which was accompanied by hydrops fetalis and polyhydramnios with an absent stomach echo. Absent pulmonary valve was diagnosed by a cystic, pulsatile, aneurysmal dilatation of pulmonary arteries and a relatively small pulmonary valve annulus without a definite valve echo, in which a typical to-and-fro flow pattern was detected by the Doppler flow analysis. We will discuss some plausible roles of the grossly enlarged pulmonary arteries on hydrops fetalis and polyhydramnios.
