Abstract
Bartonella species are Gram-negative bacilli and fastidious bacteria that can cause a number of clinical syndromes, including blood culture-negative infective endocarditis (IE). The two most commonly isolated species in humans are Bartonella quintana, the agent of trench fever, and Bartonella henselae, mostly known for causing cat scratch disease (Edouard et al., 2015 [1]; Edouard and Raoult, 2010 [2]). Both species also cause bacillary angiomatosis, primarily in immunocompromised patients (Edouard et al., 2015 [1]; Fournier et al., 2001 [3]). The risk of B. henselae IE is increased in patients with cardiac valvular disease and congenital heart disease (CHD) (Edouard and Raoult, 2010 [2]; Das et al., 2009 [4]; Abandeh et al., 2012 [5]; Ouellette et al., 2016 [6]; Hoffman et al., 2007 [7]; Georgievskaya et al., 2014 [8]). In this article, we detail two cases of Bartonella IE in patients with right ventricle-to-pulmonary artery (RV-PA) conduits who presented to our institution. We also perform a literature review on Bartonella IE in patients with a history of RV-PA conduit or pulmonary valve replacement.
