Indications
Class I / strong:
- Device infection — pocket infection or erosion, systemic infection, or lead/valvular endocarditis. Complete system removal is required.
- Lead malfunction or recall when the lead cannot be safely abandoned or reprogrammed around
Relative:
- Venous occlusion preventing an upgrade or needed lead addition
- Abandoned-lead burden, MRI need, chronic pain, or a thrombogenic/recalled lead in a younger patient
- Lead repositioning for refractory issues
Pre-procedure planning
- Define the leads: implant date, manufacturer/model, single vs dual coil, prior extractions. Lead age and ICD coils predict difficulty.
- Infection workup: blood cultures, TEE for vegetations, source control plan, and an antibiotic course; plan reimplant timing (often contralateral, after negative cultures).
- Pacing dependence: arrange temporary transvenous pacing or a plan for immediate reimplant.
- Safety net: arterial line, large-bore access, crossmatched blood, perfusion/surgery aware, hybrid OR if available.
Setup & equipment
- General anesthesia with TEE in place from the start
- Open the pocket and free the leads to the venous entry
- Cut the leads, pass the locking stylet to the distal tip and deploy
- Advance telescoping/powered sheaths over the lead to dissect binding sites at the innominate–SVC junction, SVC coil, and tip
Technique
- Counter-traction: the locking stylet holds the tip while the sheath is advanced — force is applied at the binding site, not transmitted to the myocardium
- Powered dissection: laser or rotational mechanical sheath releases dense fibrosis; bidirectional rotational tools handle calcified binding
- Femoral approach: snares (Needle’s Eye, gooseneck) retrieve free-floating, retained, or difficult leads from below
- Continuous TEE: watch for new pericardial effusion — the earliest sign of perforation
Complications
- SVC laceration — rare but often fatal without immediate rescue; deploy the SVC occlusion balloon, transfuse, and convert to sternotomy
- Cardiac tamponade — from tip avulsion or SVC tear; TEE surveillance enables early pericardiocentesis or surgery
- Vascular avulsion / hemothorax
- Tricuspid valve injury when extracting leads adherent to the valve apparatus
- Incomplete removal, lead fracture, retained fragments
Post-procedure care
- Monitor for delayed effusion; chest imaging as indicated
- Infection: complete the antibiotic course, confirm clearance, and reimplant (usually contralateral) once cultures are negative — or transition to a leadless pacemaker or S-ICD where appropriate
- Pacing-dependent patients require a bridging or definitive pacing plan before leaving the lab
