[Obstetric outcomes in women with repaired transposition of the great arteries]

Transposition of the great arteries (TGA) is a congenital heart disease whose neonatal surgical correction by atrial switch (ATSO) or arterial switch (ASO) now allows many women to reach childbearing age.

We conducted a retrospective, single-center observational study (Caen University Hospital, 1991-2024) including 14 women with TGA (33 pregnancies).

Of the pregnancies, 72.7% reached term. The miscarriage rate was comparable to that of the general population. Vaginal delivery was possible in 62.5% of cases. Only one patient (ATSO) experienced severe cardiac complications. Postpartum follow-up showed globally stable ventricular function, with no significant progression of minor aortic regurgitation after ASO or systemic right ventricular dysfunction after ATSO.

Pregnancy is generally well tolerated in women with repaired TGA, particularly.
