Endocarditis Mimicking ANCA-Associated Vasculitis.

Bacterial endocarditis presents as inflammation of the endocardium and valves of the 4 layers of the heart. The presentation and sequelae of bacterial endocarditis may vary and in certain circumstances may mimic rheumatologic disease. Antinuclear cytoplasmic antibody (ANCA)-positive bacterial endocarditis constitutes a special subgroup of bacterial endocarditis.
