May warrant surveillance for Medtronic 6972 lead failure; leaves open durability questions in larger cohorts.
Observational (n=45)

Bipolar polyurethane pacing leads (Medtronic 6972) demonstrated a 6.6% rate of insulation failure at 15 to 18 months post-implant, characterized by low impedance and inappropriate pacemaker inhibition without visible cracking.
Raymond et al. (1984) conducted an observational in Pacemaker implantation (n=45). Bipolar polyurethane leads (Medtronic 6972) was evaluated on Insulation failure. Bipolar polyurethane leads (Medtronic 6972) implanted in the right ventricle resulted in insulation failure in 6.6% of cases at 15 to 18 months post-implant.
