ABSTRACT
Objective: To compare the neonatal outcomes in pregnant women with repaired vs unrepaired congenital heart disease (CHD). Methods: Data on pregnant women with CHD was retrieved from our hospital records for the duration April, 2014 to December, 2021. Pregnant women with CHD were divided into two groups: simple CHD and moderate-tocomplex CHD. Results: In simple CHD group, neonatal outcomes were similar in pregnant women with repaired and unrepaired CHD. By contrast, in moderate-to-complex CHD group, the offspring of women with unrepaired CHD had lower gestational age [mean (SD) 34.3 (2.7) vs 36.8 (2.1) week; P=0.016] and lower birth weight [mean (SD) 2126.8 (711.9) vs 2720 (645.7); P=0.037] than those with repaired CHD. Infants of women with unrepaired moderate-to-complex CHD had a higher risk of premature delivery (87.5% vs 45.5%, P=0.013), low birth weight (81.3% vs 36.4%, P=0.04) and neonatal intensive care unit (NICU) admission (68.8% vs 27.3%, P=0.034). Conclusions: Surgical repair before pregnancy in women with moderate-to-complex CHD significantly minimized the risks of neonatal complications.
