Feasibility and efficacy of percutaneously delivered leadless cardiac pacing in an in vivo ovine model.
In this in vivo ovine study, we describe the course of pacing and sensing parameters during follow-up as well as the gross and histopathological features at the implant site of the recently described leadless cardiac pacemaker (LCP). ⋯ We demonstrate that after implantation of the LCP, pacing/sensing parameters remain adequate up to 18 months in follow-up. In addition, pathological changes at the implant site and within the RV are limited in severity at 90 days, supporting the efficacy and safety of this novel approach to pacing.
