Bacteremia following prosthetic valve replacement.

F B Parker, C Greiner-Hayes, R H Tomar

    Annals of Surgery

    Summary

    Early bacteremia after cardiac valve replacement, often gram-negative, poses significant risks. Vigilant diagnosis and treatment are crucial to prevent mortality and morbidity from sepsis.

    Area of Science:

    • Cardiovascular Surgery
    • Infectious Diseases
    • Critical Care Medicine

    Background:

    • Bacteremia following cardiac valve replacement is a serious complication.
    • Gram-negative organisms are frequently implicated in post-operative infections.

    Purpose of the Study:

    • To investigate the outcomes of early bacteremia in patients undergoing cardiac valve replacement.
    • To identify risk factors and clinical presentations associated with bacteremia post-cardiac valve surgery.

    Main Methods:

    • Retrospective analysis of 890 patients over a ten-year period.
    • Monitoring for bacteremia during the hospital recovery phase post-valve replacement.
    • Analysis of causative organisms, white blood cell counts, and patient outcomes.

    Main Results:

    • 3.6% of patients (32/890) developed bacteremia.
    • Gram-negative bacteria accounted for 60% of infections.
    • Elevated white blood cell counts (>14,000) were common.
    • Nine deaths occurred, primarily due to septic complications.
    • Endocarditis was rare (2/32), with no cases in patients diagnosed within ten days of surgery.

    Conclusions:

    • Early diagnosis and prompt treatment of bacteremia are essential to reduce mortality and morbidity.
    • Vigilance is required to manage gram-negative sepsis and prevent severe complications like endocarditis.
