Bartonella endocarditis in a child with tetralogy of Fallot complicated by PR3‐ANCA positive serology, autoimmune hemolytic anemia, and acute kidney injury

: Although the role of ANCA in infective endocarditis is unclear, Bartonella henselae has been implicated as the culprit in cases of PR3-ANCA positive subacute bacterial endocarditis (SBE) with glomerulonephritis. In this case, a Coombs-positive autoimmune hemolytic anemia and glomerulonephritis accompanied a PR3-ANCA positive SBE caused by Bartonella henselae.
