Bivalvular Bartonella henselae prosthetic valve endocarditis.
Prosthetic valve endocarditis is an uncommon manifestation of infection with Bartonella species. Herein, we report a case of Bartonella henselae endocarditis involving prosthetic mitral and aortic valves. The patient had a favorable outcome with combined medical and surgical therapy. Concomitant crescentic glomerulonephritis led to an initial mistaken diagnosis of Wegener's granulomatosis.
متن کاملDiagnosis of Bartonella henselae Prosthetic Valve Endocarditis in Man, France
To the Editor: Bartonella spp. cause 2% of cases of blood culture– negative endocarditis (1). Early diagnosis of Bartonella spp. infectious endocarditis, is challenging, especially for patients with preexisting valvular heart disease. A diagnosis for these patients requires bacterial culture, serologic testing, or molecular detection in serum or tissue (2). The sensitivity and specificity of Du...

We describe the first case of Bartonella quintana endocarditis affecting a prosthetic valve in a person with no known risk factors for this infection. Bartonella should be considered as a cause of endocarditis in any clinical setting.
متن کاملProsthetic Valve Endocarditis Caused by Bartonella henselae: A Case Report of Molecular Diagnostics Informing Nonsurgical Management
Identifying the pathogen responsible for culture-negative valve endocarditis often depends on molecular studies performed on surgical specimens. A patient with Ehlers-Danlos syndrome who had an aortic graft, a mechanical aortic valve, and a mitral anulloplasty ring presented with culture-negative prosthetic valve endocarditis and aortic graft infection. Research-based polymerase chain reaction ...
متن کاملManagement of Bartonella Prosthetic Valve Endocarditis without Cardiac Surgery
Two cases of Bartonella prosthetic valve endocarditis were cured when treated for 2 weeks with gentamicin and 3 months with doxycycline. Clinical cure correlated with decreased Bartonella antibody titers. This report suggests a strategy to monitor, treat, and cure Bartonella prosthetic valve endocarditis.
