Vasconcelos JPF, Casanova S, Domingos J, Granado J, Baptista T, Mansinho K. Granulicatella adiacens—A rare and challenging cause of endocarditis. J Case Rep Images Infect Dis 2021;4:100011Z16JV2021.ABSTRACT
Introduction: Infective endocarditis (IE) is a relatively rare but serious infection, inevitably fatal without treatment. Despite advances, its management is still challenging and often individualized. High-risk patients should be opportunely identified based on patients’ characteristics, cardiac or extracardiac complications, and the culprit infectious organism. Granulicatella adiacens, an oral commensal, is an increasingly recognized cause of IE, being a particularly virulent organism, associated to severe complications and an exceptionally challenging diagnosis and treatment.
Case Report: We report a case of G. adiacens IE in a previously healthy and immunocompetent patient, whose only risk factor was a known mild mitral regurgitation. He presented with a large and mobile vegetation, cardiac failure associated to structural cardiac damage, and silent embolic phenomena. Surgical intervention was early considered and mitral valve repair done after 7 days of directed antibiotic therapy.
Conclusion: This case emphasizes a rare, difficult to diagnose, and serious cause of IE that should be actively reminded.
