    ObjectiveTo examine trends in utilization of hearts from hepatitis C virus (HCV) viremic donors for transplantation, a strategy to expand organ availability.MethodsThe United Network for Organ Sharing (UNOS) registry was queried for adult patients undergoing heart transplantation between 2015 and 2019. We excluded multiorgan transplants, incomplete data, and loss to follow-up. Nucleic acid testing (NAT) defined HCV status.ResultsBetween 2015 and 2019, a total of 11,393 adults underwent heart transplantation: 326 from HCV NAT+ donors and 11,067 from NAT- donors. The use of NAT+ hearts increased from 1 in 2015 to 137 in 2018 against a static number of NAT- organs. The use of NAT+ hearts varied significantly across regions and individual centers. More than 75% of NAT+ hearts were transplanted in the Northeast region, leading to further travel (mean, 299 miles vs 173 miles for NAT- transplantations; P < .001), with longer ischemic times (mean: 3.52 hours vs 3.10 hours; P < .001). More than one-half of NAT+ transplantations were performed by 5 individual centers, and a single institution accounted for >20% of all transplantations from viremic donors. Survival in the 2 groups did not differ by Kaplan-Meier analysis (P = .240), and multivariable regression showed no differences in acute rejection (P = .455) or 30-day mortality (P = .490). Of the 326 recipients of NAT+ hearts, 38 seroconverted and 14 became viremic within 1 year. Survival was 100% in the viremic patients and 97.4% in seroconverted patients at 1 year.ConclusionsHeart transplantation from HCV viremic donors continues to increase but varies significantly across UNOS regions and individual centers. Short-term outcomes are comparable, but effects of seroconversion and long-term outcomes remain unclear.Copyright © 2020. Published by Elsevier Inc.
