The current United States heart allocation system faces 2 main challenges: an evolving landscape of device therapy in advanced heart failure and a rapidly increasing transplant waiting list. The proposed new heart allocation system involves expansion of the 3 tiers and enables greater distinction between different types of mechanical circulatory support devices. In this review, we discuss how the proposed revision reconciles key concerns of the current system to create a more fair and equitable allocation of hearts in the United States.
