SIR, ANCAs are frequently associated with a limited group of small vessel vasculitic syndromes, referred to as ANCA-associated small vessel vasculitis (ANCA-associated SVV) [1]. ANCA-associated SVV is the most common primary systemic small vessel vasculitis in adults and includes three categories: WG, microscopic polyangiitis and Churg–Strauss syndrome [1].
Non-infectious cardiac involvement in ANCA-associated SVV is more frequent than it is thought [2]. However, both ANCA-associated SVV with endocardial compromise and subacute bacterial endocarditis (SBE) have the many overlapped clinical manifestations including detectable vegetations by cardioechography, inflammatory signs, renal involvement and constitutional symptoms. In addition, streptococcal SBE sometimes shows positive cANCA testing [3]. Here we report a case of non-infectious endocarditis with ANCA-associated SVV, which could be diagnosed in early stage by
