Heart waitlist survival in adults with an intra-aortic balloon pump relative to other Status 2, Status 1, and inotrope Status 3 patients.

ABSTRACT:

Background

Intra-aortic balloon pump (IABP) utilization has significantly outpaced other Status 2 eligibility criteria for heart transplant. The risk of waitlist mortality of IABP-supported patients relative to other Status 2 listed patients has not been described.

Methods

We performed a retrospective analysis of all adult patients listed Status 2 for heart transplantation under the current U.S. allocation policy, using data from the United Network for Organ Sharing. Patients listed status 1 and status 3 for high-dose inotropes were included for reference. Mortality and waitlist decompensation were modeled as a function of time-varying status in cause-specific Cox survival models.

Results

We identified 3638 Status 2 listings, of whom 1676 (46%) were Status 2 due to IA
