    Description of Event or Problem · 0

    IT WAS REPORTED PER ARTICLE OF INTEREST LITERATURE REVIEW THAT THE AUTHORS AIMED TO DETERMINE IF INFLAMMATORY BIOMARKERS COULD HELP CLINICIANS IN THE CHALLENGING DIAGNOSIS OF CARDIOVASCULAR IMPLANTABLE ELECTRONIC DEVICE (CIED) ISOLATED POCKET INFECTION. THEY PERFORMED A RETROSPECTIVE ANALYSIS OF ALL PATIENTS UNDERGOING TRANSVENOUS LEAD EXTRACTION FOR CIED INFECTION AT THE UNIVERSITY OF CALIFORNIA SAN DIEGO BETWEEN 2012 AND 2022 (156 PATIENTS). DATA WERE OBTAINED FROM THE ELECTRONIC MEDICAL RECORD (EMR) AND INCLUDED PATIENT DEMOGRAPHIC, CLINICAL, ECHOCARDIOGRAPHIC, AND DEVICE CHARACTERISTICS SUCH AS DEVICE TYPE, LEAD TYPE, NUMBER OF GENERATOR REPLACEMENTS, AND INITIAL INDICATION FOR IMPLANTATION. IN THE SYSTEMIC INFECTION GROUP, 50 SUBJECTS HAD POSITIVE BLOOD CULTURES FOR INFECTIOUS PATHOGENS, AND IN THE ISOLATED POCKET INFECTION GROUP, 18 PATIENTS HAD POSITIVE BLOOD CULTURES. VEGETATIONS WERE FOUND ON 43 DEVICE SYSTEMS IN THE SYSTEMIC INFECTION GROUP. SUBJECTS IN THE ISOLATED POCKET INFECTION GROUP HAD THE FOLLOWING SIGNS AND SYMPTOMS DOCUMENTED IN THE EMR: WARMTH, ERYTHEMA, FEVER, EROSION, DRAINAGE, SWELLING, AND PAIN. IN TOTAL, 66 OF 68 PATIENTS WITH ISOLATED POCKET INFECTIONS WERE FOUND TO HAVE A POSITIVE DEVICE OR POCKET TISSUE CULTURE FOR INFECTIOUS PATHOGEN. FINALLY, 25 PERCENT OF PATIENTS WITH ISOLATED POCKET INFECTION HAD POSITIVE LEAD CULTURES. BOSTON SCIENTIFIC LEADS REPRESENTED 21 OF THE 88 SYSTEMIC INFECTION LEADS, AND 10 OF THE 68 ISOLATED POCKET INFECTIONS. BOSTON SCIENTIFIC LEADS REPRESENTED 52 OF 281 IN THE CONTROL GROUP EXTRACTED FOR NONINFECTIOUS ETIOLOGIES SUCH AS LEAD FRACTURE, LEAD PERFORATION, DEVICE MALFUNCTION, SEVERE CHRONIC PAIN CAUSED BY THE DEVICE, OR NEED FOR SYSTEM UPGRADE. NO ADDITIONAL ADVERSE PATIENT EFFECTS WERE REPORTED.
