During the study period, 64 fetuses were diagnosed with d-TGA, which was
also confirmed postnatally. Of these, 16 fetuses were excluded due to
additional cardiac anomalies or the inability to reach the mother. In
total, 48 cases were included in this series (Figure 1).
Twenty-nine percent of the neonates were female. The mean maternal age
was 30.5±6.0 years. Cesarean section was performed in 37 (77%) cases
because of prenatal detection of restrictive appearance of the FO in 5
cases, obstetric reasons in 25 cases and maternal request in 7 cases.
The median gestational age at delivery was 39 weeks (IQR 1) week.
Maternal clinical characteristics are presented in Table 1.
Prenatal genetic testing was performed in 12 fetuses, which showed no
karyotype anomalies or 22q11 microdeletion.
