Perinatal teams dealing with fetal heart disease frequently wonder which pr
egnancies might be terminated, and when delivery should take place in a spe
cialized surrounding. We present a retrospective study of 229 fetuses, in w
hich prenatal ultrasound showed a cardiac anomaly not compatible with a sta
ndard maternity ward delivery. One hundred nineteen pregnancies were termin
ated (group I) while 110 pregnancies led to the birth of a live baby (group
II). Pathology in group I was discovered earlier than in group II (24 vs.
29.3 weeks' gestation; p < 0.01), and associated malformations or chromosom
al anomalies were much more frequent in group I (80/119 vs. 9/110; p < 0.00
1). Among live born babies, three infants with transposition of the great a
rteries underwent Rashkind atrioseptostomy in the delivery room. With a min
imum follow-up of 12 months, 69 children (63%) have undergone surgery. Amon
g 92 survivors (1 child is lost to follow-up), 78 (71%) are asymptomatic an
d 14 symptomatic.
Early prenatal diagnosis of fetal heart anomalies significantly facilitates
prenatal work-up and perinatal care. We present the types of pathology hav
ing led to termination and define the situations in which children are at r
isk of perinatal hemodynamic compromise.
