    Diphtheroid endocarditis in patients with aortic valve replacement was successfully treated with a combination of antibiotics. Early management with targeted drug therapy is recommended, even with paravalvular leaks.

    Area of Science:

    • Cardiology
    • Infectious Diseases
    • Cardiac Surgery

    Background:

    • Diphtheroid endocarditis is a rare but serious complication following aortic valve replacement (AVR).
    • Prosthetic valve endocarditis (PVE) requires prompt diagnosis and effective antimicrobial therapy.

    Observation:

    • Infections predominantly affect the aortic valve in male patients.
    • Onset typically occurs within two weeks of prosthetic valve insertion.
    • Paravalvular leaks may not necessitate reoperation.

    Findings:

    • Successful treatment of diphtheroid endocarditis was achieved using a combination of penicillin, gentamycin, and erythromycin.
    • Combined drug therapy, guided by microbial sensitivities and patient response, is an effective management strategy.

    Implications:

    • This case highlights the efficacy of tailored antibiotic regimens for diphtheroid PVE.
    • Conservative management of paravalvular leaks alongside antibiotic therapy can be successful.
    • Early intervention and appropriate antimicrobial selection are crucial for favorable outcomes in PVE.
