Medtronic CapSure Z leads linked to pacing failure from microdislodgment driven by reduced surface area.
Case Report
High impedance tined steroid-eluting leads with small surface electrodes may be associated with an increased risk of microdislodgment and subsequent ventricular pacing failure.
Answers are grounded in this paper and cite their sources.
May prompt closer monitoring for pacing failure with these leads; leaves open whether electrode surface area affects microdislodgment risk.

Kikuchi et al. (2003) conducted a case report in Ventricular pacing failure. Medtronic CapSure Z family leads was evaluated on Ventricular pacing failure due to microdislodgment. Medtronic CapSure Z leads were associated with ventricular pacing failure due to microdislodgment, potentially due to their reduced electrode surface area.
