Subclavian vein stenting linked to pacemaker dysfunction due to mechanical interference.
Case Report (n=1)
Mechanical contact from a subclavian vein stent is a rare but possible cause of pacemaker lead insulation failure and dysfunction.
Insulation failure is a common cause of permanent pacemaker and implantable cardioverter-defibrillator lead failure.1–3 Most insulation failures occur inside the pacemaker pocket, from the connector to the venous entry, often implying compression between the clavicle and first rib.4,5 Damage to leads in this region are known to be often caused by soft tissue entrapment and repetitive movements rather than true bone contact.6 Lead dysfunction caused by mechanical contact with the leads has also been reported, although rarely.

Kanda et al. (2021) conducted a case report in Pacemaker dysfunction (n=1). Subclavian vein stent was evaluated. A stent placed in the subclavian vein caused pacemaker dysfunction due to mechanical interference.
