This case study details Takayasu disease in a woman, revealing giant cell granulomatous arteritis in the aorta and coronary arteries. Thrombosis in conduction system vessels and cardiac plexus inflammation contributed to arrhythmogenic alterations.

Area of Science:

  • Cardiovascular Pathology
  • Rheumatology
  • Histopathology

Background:

  • Takayasu disease is a rare, chronic inflammatory condition affecting large arteries, primarily the aorta and its branches.
  • Giant cell granulomatous arteritis is a hallmark histological feature, leading to stenosis, occlusion, or aneurysms.
  • Understanding the cardiac manifestations is crucial for managing this complex vasculitis.

Observation:

  • A case of Takayasu disease in a 46-year-old woman is presented.
  • Histological examination revealed giant cell granulomatous arteritis in the aortic arch and collateral arteries.
  • Endocarditis and granulomatous coronaritis were also identified.

Findings:

  • The study identified thrombosis of arteriolar vessels within the cardiac conduction system.

  • Inflammation extending to the cardiac plexus was observed as a basis for arrhythmogenic alterations.
  • These findings highlight potential mechanisms for cardiac dysfunction in Takayasu disease.

    • Implications:

    • This case underscores the importance of thorough cardiovascular examination in Takayasu disease patients.
    • Identifying cardiac involvement, including conduction system abnormalities, can guide therapeutic strategies.
    • Further research into the cardiac pathology of Takayasu disease may improve patient outcomes.
