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

Area of Science:

• Cardiology
• Infectious Diseases
• Obstetrics

Background:

• Infective endocarditis (IE) typically presents with predisposing cardiac conditions, substance abuse, or in elderly patients.
• Postpartum IE is exceptionally rare, with limited documented cases in medical literature.
• This report details a unique instance of enterococcal IE occurring postpartum in an otherwise healthy individual in Japan.

Observation:

• A 31-year-old Japanese woman developed Enterococcus faecalis infective endocarditis following childbirth.
• The patient had no prior significant medical history or risk factors for endocarditis.
• She underwent emergency surgery for severe mitral regurgitation and received a six-week course of antimicrobial therapy.

Findings:

• The case involved native valve endocarditis caused by Enterococcus faecalis in a postpartum woman without underlying disease.
• The exact cause remains undetermined, but potential links to prophylactic antibiotics for cesarean section and urinary catheterization are considered.
• Cefotiam use and urinary catheterization are identified as potential risk factors for nosocomial enterococcal bacteremia in this patient.

Implications:

• This case expands the understanding of Enterococcus faecalis infective endocarditis, particularly in the postpartum period.
• It underscores the importance of considering IE in postpartum women, even without typical risk factors.
• The findings suggest a need for vigilance regarding potential iatrogenic risks, such as antibiotic administration and catheterization, in susceptible postpartum patients.
