First-in-Man Use of a Modified Controller to Resolve HVAD Failure-to-Restart.

We report a case of Medtronic HeartWare ventricular assist device (HVAD) pump failure-to-restart. Despite HVAD withdrawal from the market in June 2021, up to 4,000 patients remain on HVAD support worldwide, and many are at high risk for this serious complication. This report describes the first-in-man use of a new HVAD controller that restarted a defective HVAD pump and avoided a fatal outcome. This new controller has the potential of preventing unnecessary VAD exchanges and saving lives.
