Implication
Lead repair may be a viable alternative when feasible; leaves open need for randomized trials to confirm equivalence.
Structured PICO
Does ICD sensing lead repair prevent new lead abnormalities as effectively as lead replacement in patients with sensing lead insulation breaks?
P
Population
52 patients undergoing implantable cardioverter defibrillator (ICD) sensing lead repair (n=25) or replacement (n=27) for preoperative nonphysiological sensing or intraoperative evidence of insulation break.
I
Intervention
ICD sensing lead repair utilizing a commercially available patch kit.
C
Comparator
ICD sensing lead replacement with new sensing leads.
O
Outcome
New lead abnormalities necessitating repeat lead repair or replacement.hard clinical
Repairing ICD sensing leads with insulation breaks provides equivalent long-term durability compared to lead replacement, suggesting repair is a viable strategy when technically feasible.
