BACKGROUND: Heart disease, which affects approximately 4% of pregnancies, is the leading non-obstetric cause of maternal death. It is estimated that 40% of these deaths could be prevented with a better understanding of pregnancy risks.
OBJECTIVES: To develop the Brazilian Registry of Heart Diseases in Pregnancy (REBECGA) to study the prevalence, complications, and maternal mortality associated with heart diseases during pregnancy and postpartum.
METHODS: A multicenter retrospective study of pregnancy and postpartum follow up until 12 months after delivery in women with heart diseases, including analysis of predictive variables for maternal outcomes. A two-tailed significance level of 5% was adopted for statistical analysis.
RESULTS: A total of 638 pregnant women were included, with the following diagnoses: valvular disease (37.8%), congenital heart diseases (35.7%), arrhythmias without structural heart damage (14.7%), cardiomyopathies (11.3%), and other heart diseases (6.4%). The main complications were heart failure (16.7%), arrhythmia (10.7%), and syncope (8.0%), with 18 maternal deaths (2.8%), 10 of which occurred during the postpartum period. Cesarean delivery was indicated in 62.9% of cases, with 25.7% preterm births and 3.2% fetal losses. Multivariate analysis identified WHO class IV risk classification (OR 3.51; 95% CI 1.75-7.04; p < 0.001); NYHA class III/IV (OR 2.27; 95% CI 1.12-4.60; p = 0.023), and pulmonary hypertension (OR 2.45; 95% CI 1.05-5.70; p = 0.037) as predictive variables for maternal complications and deaths.
CONCLUSIONS: REBECGA highlighted the prevalence of valvular disease, heart failure as the main complication, the postpartum period as a critical time for maternal deaths, and identified predictive risk variables for adverse pregnancy outcomes in women with heart disease.
