Pregnancy in women with cardiac disease: a one-year retrospective review of management and maternal and neonatal outcomes in a tertiary hospital in Johannesburg, South Africa.

Introduction: In South Africa, cardiac disease continues to be the most important non-obstetric cause of maternal death.

Methods: A record review of 74 pregnant women with cardiac disease was performed to determine the prevalence and outcomes of cardiac disease at Charlotte Maxeke Johannesburg Academic Hospital between January and December 2017.

Results: Rheumatic heart disease was the most common cardiac diagnosis ( = 21, 28.4%), followed by pulmonary hypertension ( = 13, 17.6%) and congenital heart disease ( = 12, 16.2%). There were one (1.4%) maternal and two (2.7%) perinatal deaths. Neonatal complications included pre-term delivery ( = 20, 32.3%) and small-for-gestational-age infants ( = 10, 16.1%). Cardiac complications ( = 30, 40.5%) included heart failure ( = 15, 20.3%), pulmonary hypertension ( = 11, 14.9%) and blood transfusions ( = 8, 10.8%).

Conclusions: Cardiac disease in pregnancy was associated with a high risk of maternal and neonatal complications. Pre-conceptual counselling and managing pregnant women at a dedicated centre by a multidisciplinary team could, however, improve outcomes.
