Tuberculous valvular endocarditis is rare, usually seen in immunocompromised individuals. This report details the first isolated case in an immunocompetent patient with severe mitral regurgitation caused by Mycobacterium tuberculosis.

Area of Science:

  • Infectious Diseases
  • Cardiology
  • Pathology

Background:

  • Tuberculous granulomas in heart valves are uncommon.
  • Typically associated with disseminated tuberculosis in immunocompromised patients.

Observation:

  • A case of isolated tuberculous valvular endocarditis in an immunocompetent patient.
  • Severe mitral valve regurgitation due to anterior leaflet perforation.
  • Mycobacterium tuberculosis cultured from mitral valve vegetations.

Findings:

  • First reported case of isolated tuberculous valvular endocarditis.
  • Demonstrates M. tuberculosis can cause isolated valvular disease in immunocompetent hosts.

Implications:

  • Highlights the diverse clinical presentations of tuberculosis.
