Do different pacemaker lead materials and designs affect long-term lead survival?
Multifilar silicone rubber insulated pacemaker leads demonstrate superior long-term survival compared to monofilar leads, providing historical benchmarks for lead quality and longevity.
Furman et al. (1995) conducted a cohort in Pacemaker implantation (n=5,405). Multifilar silicone rubber insulated leads vs. Monofilar silicone rubber leads was evaluated on Cumulative survival rate (CSR). Multifilar silicone rubber insulated pacemaker leads demonstrated superior longevity compared to monofilar leads, achieving a 15-year cumulative survival rate of 99% to 100%.
