Background: Transposition of the great arteries (TGA) is a common critical neonatal congenital heart defect. After birth, physiological shunts close rapidly, necessitating early treatment with prostaglandin infusion and balloon-atrial septostomy. Timing of delivery is challenging, balancing the risks and advantages of early-term delivery and specialized care. The aim of this study is to assess the safety of a full-term delivery policy in fetuses diagnosed with TGA. Methods: A retrospective chart review was conducted of 17 women with a prenatal diagnosis of fetal TGA at Virgen del Rocío University Hospital between 2015 and 2021. Primary outcomes included: incidence of preterm, early-term, full-term, and late-term delivery, and rate of cesarean section. Secondary outcomes included: Saturday to Sunday admission and birth, and delivery between 0:00 a.m. and 8:00 a.m. Results: Full-term birth was achieved in 94.1%, reaching a low cesarean delivery rate (17.6%). A total of 82.4% of infants were born on weekdays, and only in three of the cases (17.6%) did delivery occur between 0 a.m. and 8 a.m. The median birth weight was 3300 g. Intravenous prostaglandins were administered in all cases, and 94.1% required balloon-atrial septostomy. Conclusions: In our study favoring full-term delivery, we reduce early-term deliveries and the cesarean section rate in prenatally diagnosed TGA. |
