    The use of Impella for cardiogenic shock has increased, yet in-hospital mortality remains high at 43.5% across various institutional volumes.

  • 2

    Patients treated at high-volume institutions (Q4) had significantly lower in-hospital and 30-day mortality compared to those at low-volume institutions (Q1).

  • 3

    A nonlinear relationship exists between annual institutional volume and in-hospital mortality, with significant reductions observed at approximately 24 cases per year.

  • 4

    Higher rates of device-related complications were noted at high-volume centres, likely due to better surveillance rather than poorer clinical care.

  • 5

    The findings suggest consolidating Impella use at experienced centres may improve outcomes, emphasizing the importance of institutional volume over facility expansion.
