Objective:
To determine the maternal and fetal outcomes in pregnant patients with prior surgical correction of dextro-transposition of the great arteries.
Methods:
A retrospective review was conducted of seven pregnancies managed from 1986-1992 in four women who had surgical correction for dextro-transposition of the great arteries.
Results:
Three of the four patients had had the Mustard operation and the other had had the Rastelli operation. There were no maternal deaths. One patient who received the Mustard operation experienced functional deterioration in the last of three pregnancies, so it was terminated. Three of the remaining six pregnancies resulted in preterm deliveries, but there was no perinatal mortality and no infants had congenital heart disease.
Conclusion:
Maternal outcome can be satisfactory and the perinatal outcome good in patients with surgically corrected dextro-transposition of the great arteries.
