Background and purpose: 

 Staphylococcus lugdunensis is often misidentified as S aureus and as a rare cause of infective endocarditis. The clinical course of S lugdunensis endocarditis is aggressive and the mortality

rate is high in contrast to S epidermidis endocarditis. Most reported cases of S lugdunensis endocarditis have involved mitral or aortic valves. Herein, we present a case with isolated
tricuspid endocarditis due to S lugdunensis.


Key words:

 Endocarditis; Staphylococcus lugdunensis; Tricuspid valve
