Clinical Outcomes of Cardiac Implantable Electronic Device Infections in Octogenarians: A 20-Year Retrospective Cohort Study

Octogenarians suffering from CIED infections display highly distinct clinical and microbiological profiles, characterized predominantly by elevated rates of localized pocket infections, specific opportunistic pathogens, and a severe underlying comorbidity burden. Crucially, our findings indicate that with the application of modern extraction and management protocols, advanced age alone does not intrinsically correlate with increased in-hospital mortality. Future prevention and perioperative management strategies tailored to this rapidly expanding demographic must heavily prioritize the mitigation of pocket-related complications, particularly considering the high prevalence of concurrent anticoagulation therapy.
