Mitral stenosis in Whipple's disease

A G Rose

    Thorax
    |August 1, 1978

    Summary

    Whipple's disease can cause mitral stenosis with characteristic vegetations. This suggests a persistent infectious agent may lead to chronic rheumatic-type heart valve damage.

    Area of Science:

    • Cardiology
    • Infectious Diseases
    • Pathology

    Background:

    • Whipple's disease is a rare bacterial infection.
    • Mitral stenosis is a narrowing of the mitral valve.
    • Rheumatic fever can cause chronic heart valve deformity.

    Observation:

    • A Whipple's disease patient presented with mitral stenosis.
    • Large, firm, yellow vegetations were found on the mitral leaflets.
    • Microscopy revealed PAS-positive macrophages and rod-shaped bodies within valve tissue.

    Findings:

    • Histopathology showed macrophages containing evidence of bacterial infection.
    • Absence of Aschoff bodies ruled out typical rheumatic heart disease.
    • The observed valve damage pattern differed from rheumatic etiology.

    Implications:

    • Findings suggest a potential infectious etiology for chronic rheumatic-type valvar deformity.
    • This case expands understanding of Whipple's disease manifestations.
    • Highlights the role of persistent infectious agents in valvular heart disease.
