How to implant the Jarvik 2000 post-auricular driveline: evolution to a novel technique.

The post-auricular (PA) driveline positioning for percutaneous power delivery is a specific feature of the Jarvik 2000 FlowMaker LVAD. We applied several technical refinements to optimise the PA implant. Here, we present and discuss these modifications. We retrospectively reviewed all patients implanted with Jarvik 2000 at our Institution. Different PA implant techniques were described. A machine learning analysis was performed to evaluate the determinants of driveline infection. From December 2008 to December 2017, 62 patients were implanted with Jarvik 2000, at our Institution. The PA connection was managed through the "question mark-shaped" incision in 24 patients (39%) and with the "C-shaped" in 18 (29%), whereas 10 (16%) cases received the "vertical incision" and 10 (16%) the "orthogonal incision". The implant technique resulted highly predictive of driveline infection. The rate of driveline infections was numerically lower among cases managed with the last two techniques. After evolving through different implant techniques, we propose and suggest the "orthogonal incision" to maximise the advantages of the Jarvik 2000 post-auricular driveline.
