Rheumatic Heart Disease in Pregnancy in Sub-Saharan Africa: A Case Series Emphasizing Gaps in Access to Definitive Care

Rheumatic heart disease (RHD) remains a major cause of maternal cardiovascular morbidity and mortality in low-resource settings, particularly among women of reproductive age. Physiological changes during pregnancy can unmask previously undiagnosed disease or precipitate decompensation in those with established valvular lesions. We present a case series of three women with RHD during pregnancy and the early postpartum period, highlighting the burden, clinical presentation, and management challenge in a resource-limited setting. All patients presented with advanced disease, including severe mitral stenosis, atrial fibrillation, and heart failure, with one case complicated by multivalvular involvement and reduced left ventricular function. Management focused on hemodynamic stabilization using diuretics, rate control, anticoagulation, and multidisciplinary care. Definitive interventions such as percutaneous balloon mitral valvotomy or valve replacement were indicated but deferred due to limited availability and financial constraints. All three mothers were clinically stabilized and remained alive at short-term follow-up, although one preterm neonate died from respiratory distress syndrome and Case 3 required readmission because of medication nonadherence. This series underscores the persistent burden of RHD in pregnancy in sub-Saharan Africa and highlights critical gaps in access to definitive cardiac interventions and anticoagulation monitoring. Strengthening health systems, improving access to specialized cardiac care, and implementing preventive strategies are essential to reduce morbidity and mortality associated with RHD in pregnancy in resource-limited settings.
