Correct answer: C — Complete device extraction (generator AND all leads) plus targeted IV antibiotics for at least 2 weeks after extraction — pocket infections require COMPLETE device removal

CIED pocket infections require COMPLETE device extraction — generator AND all leads. Partial extraction (generator only with lead retention) has unacceptable failure rates (>50% relapse). Even without bacteraemia, the entire system must be removed because biofilm on the leads cannot be sterilised with antibiotics alone. After extraction: IV antibiotics for at least 2 weeks (guided by culture), then a new CIED is reimplanted at a DIFFERENT site after a device-free interval (typically 72 hours to 2 weeks depending on the organism/severity).
