Implication

Benchmarks traction forces for lead extraction simulators; leaves open clinical safety thresholds in patients.

Key Points

To measure the mechanical traction forces applied by experienced operators during transvenous ICD lead extraction on a phantom model.
Seventeen experienced physicians performed an ICD lead extraction maneuver on a torso phantom model.
Operators pulled until further traction was considered hazardous to a patient or warranted a change in extraction technique, with forces measured using a digital precision gauge.
Median traction force exerted on the endocardium was 10.9 N (range 3.0 N to 24.7 N; interquartile range 7.9 N to 15.3 N).
Forces applied at the proximal lead end were estimated to be approximately 10% higher than those at the tip due to friction loss.

Population

17 physicians experienced in transvenous lead removal performing extraction on a torso phantom

Intervention

Transvenous lead extraction manoeuvre of an ICD lead on a torso phantom

Outcome

Traction forces on the endocardium recorded with a digital precision gauge

Experienced physicians apply a median traction force of approximately 11 N during transvenous ICD lead extraction, providing a benchmark for simulator training.
