Background
- Ranges from local pocket infection to bacteremia to endocarditis
Epidemiology
- Occurs in about 2 per 1000 device-years
Clinical Manifestations
- Isolated generator pocket infection: localized erythema, swelling, pain, tenderness, warmth, or drainage, with negative blood cultures
- Isolated pocket erosion: device or lead exposed through the skin, with or without signs of infection
- Lead infection: lead vegetation with positive blood cultures
Investigations
- Blood cultures, ideally before antibiotics
- Transesophageal echocardiogram in most cases (in strong preference to transthoracic echocardiogram)
- Pacemaker pocket swab at time of removal
Management
- Management depends on blood culture findings
- If positive, get TEE
- If negative but high clinical suspicion, get TEE
- If bacteremia or prior antibiotics
- Valve vegetation ± bacteremia: remove CIED and treat as endocarditis
- Lead vegetation ± bacteremia: remove CIED and treat for 2 weeks, or 4 weeks for Staphylococcus aureus
- Negative TEE: consider CIED removal depending on microbiology and treat for 2 weeks
- If no bacteremia but TEE positive, treat as above
- If no bacteremia and no TEE or TEE negative
- Pocket site infection or erosion: remove CIED and treat for 2 weeks
- No pocket site infection: monitor
- CIED can be reimplanted when blood cultures are negative for at least 72 hours
