Association between Takayasu Arteritis and Pericardial Effusion

Characteristics of the Association

• The European Society of Cardiology classifies Takayasu arteritis as a non-infectious cause of pericardial diseases within the group of systemic vasculitis 1, 2
• The American Heart Association notes that pericardial effusions associated with vasculitis like Takayasu arteritis are generally hemodynamically insignificant 3

Diagnosis

• The diagnosis of pericardial effusion in patients with Takayasu arteritis is made using echocardiography, which allows visualization and quantification of the effusion 3
• In patients with suspected Takayasu arteritis and pericardial manifestations, laboratory tests to evaluate inflammatory markers (CRP, ESR) are recommended 4

Treatment

• The treatment of pericardial effusion associated with Takayasu arteritis includes high-dose corticosteroids as initial therapy (prednisone 40-60 mg daily) 5
• Immunosuppressive agents like methotrexate (20-25 mg/week) or azathioprine (2 mg/kg/day) can be used as steroid-sparing agents 5

Pronóstico and Follow-up

• Regular clinical evaluation and measurement of inflammatory markers (ESR/CRP) are recommended to monitor disease activity 5
• Periodic echocardiography is recommended to evaluate the resolution of the pericardial effusion 3
