Insights

The CentriMag system effectively bridges emergency heart transplant candidates to surgery, showing feasible use and acceptable survival outcomes. This acute circulatory support demonstrated comparable results for both left ventricular and biventricular support configurations.

Area of Science:

  • Cardiovascular Surgery
  • Transplantation Medicine
  • Mechanical Circulatory Support

Background:

  • Emergency heart transplantation (HTx) requires effective bridging strategies.
  • The CentriMag acute circulatory support system offers potential for bridging HTx candidates.

Purpose of the Study:

  • To describe clinical outcomes of CentriMag use as a bridge to emergency HTx.
  • To compare outcomes between left ventricular support (LVS) and biventricular support (BVS) configurations.

Main Methods:

  • Descriptive analysis of a multicenter retrospective registry (2010-2020) of 358 HTx candidates.
  • Patients received CentriMag configured for LVS or BVS, listed for high-priority HTx.
  • Primary endpoint: 1-year post-HTx survival.

Main Results:

  • 303 (84.6%) patients received HTx; 53 (14.8%) died awaiting transplant.
  • One-year post-HTx survival was 77.6%.
  • No significant survival difference between LVS and BVS groups; BVS associated with higher bleeding/renal failure, LVS with higher stroke incidence.

Conclusions:

  • CentriMag system use as a bridge to emergency HTx is feasible.
  • Acceptable on-support and posttransplant outcomes were observed.
  • Prioritization and short waiting times contribute to successful bridging.
