Abstract

© 2015 Taylor & Francis. Introduction: Recent studies pointed to an intrinsically angiogenic imbalance in CHD in the maternal and foetal circulation suggestive of impaired placentation. Objectives: To assess whether pregnant women with a CHD foetus are at greater risk of placenta-related complications. Methods: Perinatal results of women with a CDH foetus were compared with those of a non-selected population followed up at our centre. Multiple pregnancies and chromosomal abnormalities were excluded from the analysis. Results: About 279 pregnancies with CHD foetuses were included. Mothers were classified in three groups according to the foetal cardiac defect: 104 (37.3%) atrioventricular defect, 102 (36.5%) conotruncal anomalies and 73 (26.2%) left-ventricular outflow tract obstruction. A significantly higher incidence of pre-eclampsia was observed in the CHD group compared with the normal population (5.7% versus 1.2% p < 0.0001) [OR 5.96 (95% CI – 3.19–10.54)]. About 9.7% of foetuses with CHD had < 3rd birth weight percentile compared with 3% for the normal population [OR 3.32 (95% CI – 2.39–4.56)]. A higher incidence of stillbirth was also observed in the CHD group compared with the normal population (2.5% versus 0.4%) [OR 9.45 (95% CI – 3.35–23.3)]. Conclusions: Women carrying a foetus with CHD have a high risk of pre-eclampsia and intrauterine growth restriction. The relationship between CHD and placenta-related complications could be an encouraging topic for future research.
