Insights

Percutaneous ventricular assist device (PVAD) support during high-risk percutaneous coronary intervention (HRPCI) shows better outcomes than intra-aortic balloon pump (IABP) support. PVAD-assisted HRPCI is linked to lower mortality and fewer complications.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Medical Devices

Background:

  • High-risk percutaneous coronary intervention (HRPCI) often requires mechanical circulatory support.
  • Percutaneous ventricular assist devices (PVAD) and intra-aortic balloon pumps (IABP) are commonly used for HRPCI.
  • Outcomes comparing PVAD and IABP in HRPCI are not well-defined in large contemporary datasets.

Purpose of the Study:

  • To compare the clinical outcomes of PVAD-supported versus IABP-supported HRPCI.
  • To evaluate 90-day mortality and major adverse cardiac and cerebrovascular events (MACCE).
  • To assess secondary outcomes including cardiogenic shock, acute kidney injury, and length of stay.

Main Methods:

  • Retrospective analysis of a large hospital administrative dataset (Premier Healthcare Database) from January 2018 to April 2024.
  • Inclusion of patients undergoing HRPCI with PVAD or IABP support, excluding specific high-risk subgroups (e.g., cardiogenic shock, STEMI).
  • Variable rate propensity score matching using 87 preprocedural variables to balance patient and provider characteristics.

Main Results:

  • PVAD support was associated with significantly lower 90-day mortality (7.9% vs 11.8%) and MACCE (10.3% vs 14.9%) compared to IABP support.
  • PVAD-supported patients experienced less postprocedural cardiogenic shock (9.5% vs 23.5%) and acute kidney injury (9.9% vs 15.6%).
  • PVAD support resulted in shorter lengths of stay (4.3 vs 5.7 days) and higher rates of home discharge.

Conclusions:

  • PVAD-supported HRPCI in non-shock patients may offer improved clinical outcomes compared to IABP support.
  • The findings suggest a potential benefit of PVAD over IABP in this patient population.
  • Further confirmation through randomized controlled trials is warranted to validate these observational findings.
