Purpose of review The revised United States heart organ allocation system was launched in October 2018. In this review, we summarize this United Network for Organ Sharing (UNOS) policy and describe intended and unintended consequences. Recent findings Although early studies published after the change suggested postheart transplant survival declined at 6 months and 1 year, recent publications with longer follow-up time have confirmed comparable posttransplant survival in adjusted models and several patient cohorts. Moreover, the new allocation decreased overall waitlist time from 112 to 39 days ( P < 0.001). Mean ischemic time increased because of greater distances traveled to acquire donor hearts under broader sharing. Despite the intention to decrease exception requests by expanding the number of priority tiers to provide more granular risk stratification, ∼30% of patients remain waitlisted under exception status. Left-ventricular assist device (LVAD) implants are declining and the number of LVAD patients on the transplant list has decreased dramatically after the allocation system change. Summary As the next allocation system is developed, it is imperative to curtail the use of temporary mechanical support as a strategy solely for listing purposes, identify attributes that more clearly stratify the severity of illness, provide greater oversight of exception requests, and address concerns regarding patients with durable LVADs.
