[Late-onset postpartum sepsis with septic shock and heart dysfunction].

We report a case of late-onset postpartum sepsis from endometritis due to group A streptococci (GAS) in a 37-year-old white woman. The patient developed septic shock, with mitral regurgitation and cardiac dysfunction. Early treatment with broad-spectrum antibiotics and hemodynamic support was essential for a favorable outcome. Because of the resurgence of virulent strains of GAS that can cause fatal infections, these pathogens should be included in the differential diagnosis of postpartum infections in the mother. Although cardiac dysfunction is rare in association with GAS infection, it should be ruled out by echocardiography when the condition of a patient with sepsis does not improve.
