Background Severe valvular heart disease, especially stenosis, is a contraindication for conception according to the World Health Organization. This is still encountered in countries with a high rheumatic fever prevalence. The objective of this study was to determine predictors of maternal cardiac, obstetric and neonatal complications in pregnant women with severe valve disease. Methods This is an observational retrospective cohort study of all pregnant women with severe heart valvulopathy who gave birth between 2010 and 2017. Results We included 60 pregnancies in 54 women. Cardiac complications occurred during 37 pregnancies (61%). In multivariate analysis, parity (aOR =2.41, 95% CI[1.12–5.16]), revelation of valvulopathy during pregnancy (aOR = 6.34; 95% CI[1.26–31.77]), severe mitral stenosis (aOR = 6.98, 95% CI[1.14–41.05],) and systolic pulmonary arterial pressure (aOR =1.08, 95% CI[1.01–1.14]) were associated with cardiac complications. Obstetrical complications were noted during 19 pregnancies (31.8%). These complications were associated with nulliparity (aOR = 5.22; 95% CI[1.15–23.6]), multiple valve disease (aOR = 5.26, 95% CI[1.19–23.2]), systolic pulmonary arterial pressure (aOR =1.04, 95% CI[1.002–1.09]), and treatment with vitamin K antagonists (aOR = 8.71, 95% CI[1.98–38.2]). Neonatal complications were noted in 39.3% of newborns ( n  = 61) and these were associated with occurrence of obstetric complications (aOR = 16.47, 95% CI[3.2–84.3]) and revelation of valvulopathy during pregnancy (aOR = 7.33, 95% CI[1.4–36.1]). Conclusions Revelation of valvular heart disease during pregnancy is a predictor of not only cardiac but also neonatal complications. Valvular heart disease screening during pre-conceptional counseling is thus crucial.
