Bartonella endocarditis with glomerulonephritis in a patient with complete transposition of the great arteries.

We describe a patient with history of dextro-transposition of the great vessels, ventricular septal defect, and pulmonary valve replacement who presented with fatigue, prolonged fever, and leg edema. He was found to have kidney injury, pancytopenia, and liver congestion. Echocardiogram revealed thickened leaflets with prolapsing vegetation on the pulmonary valve. Given the negative blood cultures, high Bartonella henselae immunogobulin G titer (≥1:1024) and positive immunoglobulin M titer (≥1:20), he was diagnosed with Bartonella endocarditis complicated with glomerulonephritis.
