Cardiac Device Infection Management and Lead Extraction Techniques
Summary
Cardiac implantable electronic devices (CIEDs), including pacemakers, defibrillators and cardiac resynchronisation systems, have transformed the treatment of arrhythmias and heart failure. However, pocket infections and systemic device-related infections remain a serious complication, often necessitating complete device removal. Effective management combines prompt diagnosis, targeted antimicrobial therapy and either early or delayed re-implantation strategies to balance infection eradication against patient stability. Prevention has become equally critical, with innovations such as antimicrobial coatings, biofilm-resistant materials and leadless pacing platforms that minimise hardware exposure. When extraction is required, transvenous lead extraction (TLE) employs specialised sheaths—mechanical, laser or rotational—to free fibrotic adhesions and remove leads with minimal trauma. Risk stratification tools, incorporating factors such as lead dwell time, patient comorbidities and procedural history, guide referral to high-volume centres with surgical backup to reduce complications. Recent advances include improved imaging for adhesion mapping, refined extraction algorithms and hybrid surgical approaches for complex cases. Together, these strategies aim to reduce morbidity, shorten hospitalisation and improve long-term survival in patients facing device infection.

Cardiac Device Infection Management and Lead Extraction Techniques publication trend
The graph below shows the total number of articles in cardiac device infection management and lead extraction techniques across all publications each year (not limited to Nature Index journals).
Technical terms
Cardiac implantable electronic device (CIED): A device implanted within the body to monitor or correct cardiac rhythm disorders, such as pacemakers or defibrillators.
Pocket infection: Local infection of the subcutaneous tissue where a CIED generator is implanted, often presenting with redness, swelling or discharge.
Transvenous lead extraction (TLE): The percutaneous removal of pacing or defibrillator leads via the venous system using specialised sheaths.
Lead dwell time: The duration a lead has been implanted, which correlates with the extent of fibrotic adhesions.
Biofilm: A microbial community adherent to device surfaces, embedded within a self-produced extracellular matrix that confers resistance to antibiotics.
