Infective endocarditis due to Bartonella bacilliformis is rare. A 64-year-old woman, without previous heart disease, presented with 6 weeks of fever, myalgias, and arthralgias. A systolic murmur was heard on the tricuspid area upon examination, and an echocardiogram showed endocardial lesions in the right atrium. Bartonella bacilliformis was isolated in blood cultures, defining the diagnosis of infective endocarditis using Duke’s criteria. Subsequently, the patient developed clinical and laboratory features compatible with antineutrophil cytoplasmic antibody-associated vasculitis. This case presents an uncommon complication of B. bacilliformis infection associated with the development of systemic vasculitis.

La Bartonelosis (también llamada Enfermedad de Carrión o Verruga Peruana) es una enfermedad clásica de la medicina peruana. En las últimas dos décadas se han producido nuevos conocimientos e investigacio- nes, que han roto muchos paradigmas de esta enfer- medad, los cuales son presentadas en esta revisión.

Introduction: Carrion’s disease is considered a re-emerging disease in Peru, and it leads to several non-infectious and infectious complications.Objectives: To assess cardiovascular complications (CC) during the acute phase of this disease.Methods: An observational study was conducted at Cayetano Heredia Hospital (HNCH) from 1987 to 2007. Adult patients with a confirmed diagnosis of Bartonellosis were included.  Results: 68 patients were included (52 males, mean age 25,7 years). No one had prior cardiovascular disease. Main clinical findings were: fever (99%), hepatomegaly (79%), jaundice (74%), tachycardia (74%), tachypnea (71%), systolic murmur (68%), dyspnea (62%), hepatojugular reflux (19%) and jugular ingurgitation (15%). Sixty-four chest X-ray films showed the following findings: 44% cardiomegaly, 20% pulmonary congestion, and 16% pleural effusion. Transth...
