Key result
The CapSure Z lead significantly reduced the mean current drained from the pacemaker compared to traditional leads (0.42 microA vs 0.85-1.54 microA), potentially increasing pacemaker longevity.
Why the study?
Does a very small surface area steroid-eluting pacing lead improve electrical performance and reduce current drain compared to traditional leads in patients receiving dual chamber pacemakers?
Population
188 patients (105 males and 83 females; mean age 71 +/- 7 years) implanted with a dual chamber pacemaker

Does a very small surface area steroid-eluting pacing lead improve electrical performance and reduce current drain compared to traditional leads in patients receiving dual chamber pacemakers?
The use of very small surface area steroid-eluting leads significantly reduces current drain, which combined with low energy output programming can increase pacemaker longevity.
MORACCHINI et al. (1999) conducted a cohort in Dual chamber pacemaker implantation (n=188). CapSure Z lead vs. Target Tip, CapSure, and CapSure SP leads was evaluated on Mean current drained from the pacemaker (ventricular lead). The CapSure Z lead significantly reduced the mean current drained from the pacemaker compared to traditional leads (0.42 microA vs 0.85-1.54 microA), potentially increasing pacemaker longevity.
