Tricuspid Valve Endocarditis due to Klebsiella
Introduction
Infective endocarditis is an infection of the cardiac endothelium, macroscopically seen as vegetation. In the general population (including NIDU) and inthe presence of rheumatic valve disease, endocarditis occurs more frequently on the mitral valve followed by aortic valve. The incidence has remained constant over the last 30 years but the spectrum of underlying cardiac conditions and the causative organisms have changed over time .
In Intravenous Drug Users (IDUs), endocarditis is mainly on the tricuspid valve. Tricuspid valve endocarditis has also been reported among the general population, including 9% of NIDUs. Staphylococcus aureus has been implicated in most tricuspid valve endocarditis, while Escherichia coli and Pseudomonas aeuroginosa have been reported in only sporadic cases. However, Klebsiella species is an uncommon cause of endocarditis. This may be due to its poor adherence to cardiac valves compared to other organisms commonly responsible for the disease......
