Enterococcal endocarditis following sigmoidoscopy and mitral valve prolapse.

J Rigilano, R Mahapatra, J Barnhill

    Archives of Internal Medicine
    |April 1, 1984
    PubMed
    Summary

    Antimicrobial prophylaxis for infective endocarditis is debated for routine sigmoidoscopy in heart valve disease patients. This case highlights a potential risk of endocarditis following sigmoidoscopy in mitral valve prolapse patients.

    Area of Science:

    • Cardiology
    • Infectious Diseases
    • Gastroenterology

    Background:

    • Routine sigmoidoscopy can cause transient bacteremia, posing a risk for infective endocarditis in susceptible individuals.
    • The necessity of antimicrobial prophylaxis for infective endocarditis during routine sigmoidoscopy in patients with valvular heart disease remains controversial.
    • Mitral valve prolapse (MVP) is a condition that may increase the risk of developing infective endocarditis from bacteremia.

    Observation:

    • A 67-year-old male patient with a known history of mitral valve prolapse (MVP) underwent a routine sigmoidoscopy.
    • Following the procedure, the patient developed enterococcal endocarditis.

    Findings:

    • This case represents the first reported instance of enterococcal endocarditis developing after a routine sigmoidoscopy in a patient with mitral valve prolapse (MVP).

    Related Experiment Videos

  • The findings suggest a potential causal link between routine sigmoidoscopy and the development of infective endocarditis in patients with MVP, even without biopsy.

    • Implications:

    • This case underscores the need to reconsider current guidelines on antimicrobial prophylaxis for infective endocarditis in patients with mitral valve prolapse undergoing routine sigmoidoscopy.
    • Further research is warranted to clarify the risks and benefits of antibiotic prophylaxis in this specific patient population.
    • Clinicians should be aware of the potential for infective endocarditis following sigmoidoscopy in patients with underlying valvular heart conditions like MVP.
