title: Mitral and aortic valve endocarditis due to Staphylococcus lugdunensis.
abstract: Staphylococcus lugdunensis is a recently described coagulase negative staphylococcal species involved in human infections. Endocarditis caused by Staphylococcus lugdunensis has been reported rarely: fewer than 50 cases have been described so far. The infection is frequently complicated by embolic events and carries a high mortality rate. We report a case of endocarditis due to Staphylococcus lugdunensis in which the native mitral and aortic valves were infected. The bacterium was isolated on cultures from the aortic and mitral vegetations. Appropriate medical and surgical treatment led to a good 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.
