Objectives
Cardiac implantable electronic devices (CIED) have been increasingly used in recent years. These devices have been used in many clinical conditions from bradyarrhythmias to ventriculer tachycardia, and heart failure. The incidence of infection has ranged from 0.13 % to 19.9% in the literature. CIED infection leads to increased morbidity and mortality. The purpose of this study was to evaluate the duration of infection outbreak in patients who had CIED infection, and microbiological and treatment properties of CIED infections.
Method
This case-control study conducted between the years 2010-2014 includes 211 patients with implanted devices in our center. Files of the patients with CIED infection were retrospectively evaluated. After implantation, the emergence of infectious period, age, biochemical markers of infection, echocardiographic findings, pocket culture, blood culture, antibiotic regimens time and removal of the device data were recorded for each patient.
Result
CIED infection was detected in 18 of the 211 patients included in the study (8.5%). Five patients had infection within 2 months (27.7%). Erythrocyte sedimentation rates were normal in 16 patients (88.8%). CIED pocket cultures were positive in 12 patients (66.6%). Eleven of 12 patients had coagulase-negative Staphylococcus (91.6%). One patient had Rhizopus species. None had blood culture positivity. Only one patient had oscilating vegetation on the lead. Minimum duration of antibiotic use was 14 days, extended maximally to 24 days. Thirteen of 18 infected devices were removed (72.2%).
