Endocarditis is a severe, progressive disease. Coagulase-negative Staphylococci are uncommon causes of native-valve endocarditis.We present a case of endocarditis caused by Staphylococcus warneri, the evolution, diagnostic and therapeutic difficulties. In a patient known with mitral stenosis after a bronchopneumonia, fever, atrial fibrillation and congestive heart failure appeared. Vegetations on the mitral valve and positive hemocultures with Staphylococcus warneri confirmed the presumed diagnosis of endocarditis. Complications (trombocitopaenia, renal failure), diabetes and uroinfection , as well as the pluriallergy of the patient (to Penicillin , Vancomicin) made treatment very difficult. After 6 weeks of treatment the patient was better, but transesophagial echocardiography revealed trombi in her left atrium and appendix, she had subfebrility, so she went on surgery. Her mitral valve had been replaced and the trombi had been removed. Postoperative evolution was good.
