abstract

  • ObjectiveTo perform a systematic review and meta-analysis of maternal/fetal outcomes in pregnant women with moderate/severe native valvular heart disease (VHD) from medium/higher Human Development Index (HDI) countries.MethodsOvidSP platform databases were searched (1985-January 2019) to identify studies reporting pregnancy outcomes in women with moderate/severe VHD. The primary maternal outcome was maternal mortality. The primary fetal/neonatal outcome was stillbirth and neonatal death. Pooled incidences and 95% confidence intervals (CI) of maternal/fetal outcomes could only be calculated from studies involving mitral stenosis (MS) or aortic stenosis (AS).ResultsTwelve studies on 646 pregnancies were included. Pregnant women with severe MS had mortality rates of 3% (95% CI, 0% to 6%), pulmonary oedema 37% (23%–51%) and new/recurrent arrhythmias 16% (1%–25%). Their stillbirth, neonatal death and preterm birth rates were 4% (1%–7%), 2% (0%–4%), and 18% (7%–29%), respectively. Women with moderate MS had mortality rates of 1%(0%–2%), pulmonary oedema 18% (2%–33%), new/recurrent arrhythmias 5% (1%–9%), stillbirth 2% (1%–4%) and preterm birth 10%(2%–17%).Pregnant women with severe AS had a risk of mortality of 2% (0%–5%), pulmonary oedema 9% (2%–15%), and new/recurrent arrhythmias 4% (0%–7%). Their stillbirth, neonatal death and preterm birth rates were 2% (0%–5%), 3% (0%–6%) and 14%(4%–24%), respectively. No maternal/neonatal deaths were reported in moderate AS, however women experienced pulmonary oedema (8%; 0%–20%), new/recurrent arrhythmias (2%; 0%–5%), and preterm birth (13%; 6%–20%).ConclusionsWomen with moderate/severe MS and AS are at risk for adverse maternal and fetal/neonatal outcomes. They should receive preconception counseling and pregnancy care by teams with pregnancy and heart disease experience.
