Background: Increasing of Cardiac implantable electronic devices (CIEDs) have induced several complications such as infections. Our aim was to investigate the frequency of CIED infection, analyze the microbiological status and determinate contributing factors in order to prevent it. Patients and methods: We conducted a retrospective and descriptive study of patients who underwent implantation of electronic cardiac device in cardiology B department from January 2011 to June 2019. A total of 23 cases of CIED infection were identified. For each patient, all data were recorded about initial implantation of device and about CIED infection. Results: Frequency of CIED infection in our study is 1.2%. According to British guidelines, isolated local infection (uncomplicated PI) is observed in 8 patients (34.7%), local infection associated with sepsis (complicated PI) is found in 8 cases (34.7%) and 5 patients (21.7%) presented with systemic signs (ICED-LE and ICED-IE). Infection involve 17 patients with primary implantation and 6 patients after generator replacement.78% of patients, male and 56% are young and (≤60 years) and 39% are diabetics series is characterized by largest number of patients (78%) who consult for local signs. Biological assessment and blood cultures didn’t help to differentiate between local et systemic forms because blood tests were often negative. We noticed an increased negativity of bacteriological examinations. Conclusion: ICED-related infection affects, mainly, young male patients and frequently diabetics. These patients usually have been surgically revised for postoperative complications or underwent temporary wire before implantation. Often, it is systemic form induced by pocket infection. Biological and bacteriological tests are always negative. When the causative germ is isolated, it is often staphylococcus. Thus, implantation of CIED in these patients must be carefully performed especially in diabetics. Surgical revisions have to be avoided....
