Abstract Infective endocarditis is a rare but serious complication of permanent cardiac pacing with high mortality ranging from 10 to 30\%. Clinical symptoms are sometimes acute but more often poor and aspecific in subacute and chronic forms causing prolonged diagnostic delay. In order to make endocarditis on pacemaker leads clearer, we conducted a medline search of all published literature. Analysis of this literature shows that the initial infective source is often local and that Staphylococcus species are the most often pathogens isolated. Clinicians have to search carefully for local inflammatory signs, past or ongoing, and pulmonary embolism because their presence will be helpful for diagnosis. Transoesophageal echocardiography is essential; it shows vegetations in more than 90\% and must be repeated when the examination is negative. Treatment has a double goal: a prophylactic treatment in order to reduce risk factors of infection related to implantation of the pacemaker and a curative treatment associating prolonged antibiotic therapy with extraction of the material.
