Objectives: We aimed to investigate the demographic and clinical characteristics, echocardiographic and microbiologic features, and outcomes of patients with permanent pacemaker (PM), and implantable cardioverter-defibrillator (ICD) - related endocarditis in this study.,Study design: The study population consisted of 15 patients with permanent PM and ICD-related endocarditis. Data on patients'demographic characteristics, medications used, clinical, and microbiological data, echocardiographic findings, types, and outcomes of surgical treatments were recorded.,Results: The mean age of the patients was 57+/-16. Seven patients (47%) were female. Of the 15 patients with permanent PM and ICD-related endocarditis, 5 died during in-hospital follow-up (33%). In four patients (27%) pulmonary embolism developed. Culture-negative endocarditis was detected in 5 cases (33%). Staphylococci were the most common causative organisms in 60% of the patients. Three (20%). patients underwent surgical treatment,Conclusion: Cardiac device-related endocarditis remains a rare complication of intracardiac device implantation still with higher mortality rates.
