Obstetrical outcomes in cases of maternal heart disease with a risk of cardiac decompensation: A retrospective study since the establishment of a multidisciplinary consultation meeting "heart and pregnancy".

BACKGROUND:Pregnant women with chronic heart failure (CHF) are at increased risk for cardiac complications. However, the frequency of obstetrical and neonatal complications in pregnant women with CHF remains unclear. OBJECTIVE:The objective of our study was to describe obstetrical and neonatal outcomes in pregnant with CHF. METHOD:This single-center retrospective cohort study involves pregnant women with a CHF who delivered at Jeanne de Flandre, the Lille's university hospital, from 2017 to 2021. The frequency of obstetrical, neonatal, and cardiovascular complications was collected. RESULT:During this period, we identified 26 pregnant women with a CHF. The main cardiac diseases responsible for CHF were cardiomyopathies (53.8%) and congenital heart disease (46.2%). Acute heart failure occurred in 30.8% of the cases and mainly concerned patients with no follow-up of their heart disease. The main obstetrical complications were fetal growth restriction (38.5%) and premature rupture of fetal membranes (19.2%). The 26 pregnancies comprised 25 live births and 1 stillbirth. Newborn infants were delivered via cesarean in 69.2%. Of the live births, 60% were preterm at a median gestational age of 36 (34-38) weeks. CONCLUSION:Pregnant women with CHF had a higher risk for obstetrical and neonatal outcomes.
