Mitral valve replacement for mitral stenosis caused by Libman-Sacks endocarditis.

K C Vaughton, D R Walker, M F Sturridge

    British Heart Journal
    |June 1, 1979
    PubMed
    Summary

    Libman-Sacks endocarditis caused mitral stenosis, requiring valve replacement. Despite immunosuppression, the verrucous endocarditis recurred, leading to severe prosthetic valve dysfunction.

    Area of Science:

    • Cardiology
    • Rheumatology
    • Pathology

    Background:

    • Libman-Sacks endocarditis is a rare form of nonbacterial thrombotic endocarditis associated with autoimmune diseases, particularly systemic lupus erythematosus.
    • Mitral stenosis is a significant complication that can arise from Libman-Sacks endocarditis, leading to hemodynamic compromise.

    Observation:

    • A case study detailing a woman with Libman-Sacks endocarditis who developed mitral stenosis.
    • The patient underwent successful mitral valve replacement with a Starr-Edwards prosthesis.

    Findings:

    • Despite treatment with steroids and azathioprine, verrucous endocarditis progressed one year post-surgery.
    • The progression of endocarditis resulted in sudden and severe dysfunction of the prosthetic mitral valve.

    Implications:

    • This case highlights the potential for Libman-Sacks endocarditis to recur and affect prosthetic valves, even with immunosuppressive therapy.
    • It underscores the importance of vigilant monitoring for recurrent endocarditis in patients with a history of Libman-Sacks endocarditis, especially after valve replacement.
