Large microaxial pump systems (Impella 5.0, or Impella 5.5; i.e., Impella 5+) (Abiomed Inc., Danvers, MA, USA) have gained increasing levels of attendance as valuable tools of mechanical circulatory support (MCS). Patients undergoing heart transplantation (HTX) often need temporary MCS in the perioperative course, either as a preoperative bridge or occasionally in the early post-transplant period. Here we present our experience using Impella 5+ support for patients designated to undergo HTX, describe technical aspects of implantation and removal, and further analyze factors influencing the overall patient outcome. Significant factors are discussed in front of the background of contemporary international literature, and current scientific questions are highlighted.
