Reassessing Recipient Mortality Under the New Heart Allocation System: An Updated UNOS Registry Analysis.

ABSTRACT:

Background

An early report of recipient heart transplantation outcomes under the new U.S. heart allocation system introduced in late 2018 found a lower post-transplant survival rate compared with that of the prior system.

Objectives

The aim of this study was to examine recipient survival under the new system by using an updated dataset.

Methods
