Congenital heart disease (CHD) increases the risk of adverse maternal and neonatal outcomes. However, previous studies have included mainly women with low-risk features. A single-center, retrospective analysis of pregnant women with CHD was performed. Inclusion criteria were the following high-risk congenital lesions and co-morbidities: maternal cyanosis; New York Heart Association (NHYA) functional class >II; severe ventricular dysfunction; maternal arrhythmia, single ventricle (SV) physiology, severe left-sided heart obstruction and severe pulmonary arterial hypertension. Multivariate analyses for predictors of adverse maternal cardiovascular and neonatal outcomes were performed. Forty-three women reported 61 pregnancies. There were no maternal or neonatal deaths. Maternal cardiac (31%) and neonatal (54%) complications were frequent. The most frequent cardiac events were pulmonary edema, arrhythmia, and reduced NYHA class. Previous arrhythmia conferred a 12-fold increase in the odds of experiencing at least one major cardiac complication. Maternal SV physiology was an independent risk factor for low birth weight, risk of neonatal intensive care unit admission and lower gestational age. Maternal cyanosis and severe pulmonary arterial hypertension also predicted adverse neonatal outcomes. In conclusion, mothers without antepartum arrhythmia or functional incapacity are unlikely to experience arrhythmias or a decrease in NYHA class during pregnancy. In addition, SV physiology is a robust predictor of neonatal complications. Antepartum counseling and assessment of maternal fitness are crucial for the woman with CHD.
