Mitral and aortic valve endocarditis - Due to Staphylococcus lugdunensis

Staphylococcus lugdunensis is a recently described coagulase negative staph ylococcal species involved in human infections. Endocarditis caused by Stap hylococcus lugdunensis has been reported rarely: fewer than 50 cases have b een described so far. The infection is frequently complicated by embolic ev ents and carries a high mortality rate. We report a case of endocarditis du e to Staphylococcus lugdunensis in which the native mitral and aortic valve s were infected. The bacterium was isolated on cultures from the aortic and mitral vegetations. Appropriate medical and surgical treatment led to a go od outcome of the infection. At 6-year follow-up, there was no evidence of recurrence, and the patient showed good functional recovery. He was in New York Heart Association functional class I.
