Gynecological Complications in Female Patients with Left Ventricular Assist Device Support

Staphylococcus-induced proliferative glomerulonephritis and cerebral hemorrhage - fatal complications in a young female with postpartum cardiomyopathy and an implanted left ventricular assist device: a case report and review of the literature

Background: The continuous-flow left ventricular assist device (CF-LVAD) is used to save the lives of patients in the final stage of congestive heart failure, replacing the pump function of the left ventricle. Although quality of life increases significantly, CF-LVAD-related complications might prove fatal, as in the case presented in this paper.Methods: A 20-year-old female, during her second pregnancy, presented with signs of heart failure. Emergency caesarean section was necessary to save the baby, but peripartum cardiomyopathy developed in the mother. The use of an implantable cardioverter-defibrillator (ICD) was necessary 5 years later. As the clinical progression was unfavorable under medical treatment, with the patient reaching INTERMACS (Interagency Registry for Mechanically Assisted Circulatory Support) Profile 1 (refractory cardiogenic shock), the treatment of choice was the implantation of a CF-LVAD.Results: After 3 years of follow-up (at the age of 28), the patient presented with a positive hemoculture for Staphylococcus aureus. Prolonged antibiotic therapy and attentive follow-up was prescribed. Although an effective antiplatelet and anticoagulant treatment was applied, and despite therapeutic values of prothrombin time and international normalized ratio (INR), the patient died as result of a fatal cerebral hemorrhage. The autopsy also revealed septic emboli, disseminated intravascular coagulation, and focal proliferative glomerulonephritis.Conclusions: Although the benefits of CF-LVAD are significant, bleeding episodes can be severe and LVAD-associated infection can trigger glomerular injury and increase mortality.
