Postpartum infective endocarditis with Enterococcus faecalis in Japan: a case report.

BACKGROUND

The clinical characteristics of infective endocarditis include the presence of predisposing cardiac disease, a history of illegal drug use, and high morbidity in the elderly. Only a few cases of the disease after delivery have been reported in the literature. We describe here a first case of enterococcal postpartum infective endocarditis without underlying disease in Japan.

CASE PRESENTATION: We report the case of a 31-year-old Japanese woman with postpartum infective endocarditis by Enterococcus faecalis. She had no significant medical history or any unusual social history. After emergency surgery for severe mitral regurgitation and antimicrobial treatment for 6 weeks, she was discharged from our hospital and is now being monitored at an out-patient clinic.

CONCLUSIONS

We encountered a case of Enterococcus faecalis infective endocarditis that occurred in the native valve of a postpartum healthy woman. Although the pathogenesis of this case remains unclear, it could be due to bacteremia arising from the administration of prophylactic broad-spectrum antibiotics used for cesarean section. Previous use of cefotiam and urinary catheter insertion may be risk factors for nosocomial enterococcal bacteremia in this case.
