Revisiting the Acute Performance of the 5086 MRI Lead: Coincidences or Signs?

Acute complications resulting from perma-nent pacemaker implantation are well knownand include perforation of the right atrium orright ventricle. With the current high-standardsafety parameters of pacing leads, maintainingsafety and reliability is crucial and, when theyappear, new innovations must withstand safetytests. The Medtronic CapSureFix SureScan 5086magnetic resonance imaging (MRI) transvenouslead (Medtronic Inc., Minneapolis, MN, USA)—a modified version of CapSure-Fix Novus 5076lead—has been specifically designed to functionin the MRI environment and, due to its widerwire diameter, it is overall slightly larger thanits predecessor. The 5086 MRI lead’s increaseddiameter and stiffness are its main drawbacksand may result in a greater risk of implantcomplications.Previous experience and initial data suggestthat this new lead is safe and may allowpacemaker patients to undergo MRI.
