Highlights |
• | Infective endocarditis due to Neisseria elongata is a rare disease primarily affecting the left cardiac valves. |
• | Neisseria elongata presents similarities with the HACEK group organisms and can potentially cause infective endocarditis. |
• | Embolic complications are common. Medical treatment usually suffices to ensure a satisfactory outcome. |
Abstract |
Introduction |
Neisseria elongata (NE), a Gram-negative, rod-shaped organism, was previously thought to be non-pathogenic. However, in recent years it has become increasingly recognized as a rare cause of infective endocarditis. In this paper, we report a case of NE infective endocarditis and provide a review of the literature.
Objectives |
To describe a case of NE endocarditis, and to review the literature in search of any similar cases of this rare condition.
Case report |
Our patient is a 77-year-old, otherwise healthy female patient who was found to have mitral valve endocarditis with valve regurgitation.
Discussion |
NE endocarditis is a rare condition that typically affects the left cardiac chambers and is associated with high risk of embolization. A literature review retrieved 35 other cases.
Conclusions |
Our report underlines the rarity of NE endocarditis, insofar as relatively few cases have been reported. The bacterium presents similarities with HACEK organisms and can potentially cause infective endocarditis.
