Pulmonary valve gonococcal endocarditis. A forgotten disease.

M H Rosoff, M V Cohen, G Jacquette

    British Heart Journal
    |September 1, 1983
    PubMed
    Summary

    Gonococcal endocarditis of the pulmonary valve is rare but possible. Echocardiography aids diagnosis in unclear cases, especially with sterile blood cultures.

    Area of Science:

    • Infectious Diseases
    • Cardiology
    • Medical Microbiology

    Background:

    • Gonococcal infections of the pulmonary valve were historically common but are now rare due to antibiotic availability.
    • Penicillin has significantly reduced the incidence of gonococcal endocarditis.

    Observation:

    • An elderly male presented with non-specific symptoms and a late-developing pulmonary murmur.
    • Initial blood cultures were sterile, complicating the diagnosis of endocarditis.
    • Echocardiography confirmed endocarditis localized to the pulmonary valve.

    Findings:

    • Diagnosis was delayed for three weeks due to non-specific symptoms and sterile blood cultures.
    • M-mode and cross-sectional echocardiography were crucial in localizing the endocarditis to the pulmonary valve.
    • This case highlights a rare presentation of gonococcal endocarditis.

    Implications:

    • Echocardiography is a valuable tool for diagnosing endocarditis in patients with fever of unknown origin.
    • Clinicians should consider gonococcal infection in cases of pulmonary vegetations with sterile blood cultures.
    • This case underscores the importance of considering rare pathogens in endocarditis diagnosis.
