Background The advent of direct‐acting antivirals has helped to increase the safe utilization of organs from hepatitis C virus positive (HCV+) donors. However, the outcomes of heart transplantation (HT) using an HCV+ donor are unclear in recipients with underlying liver disease represented by an elevated model for end‐stage liver disease excluding international normalized ratio (MELD‐XI). Methods The United Network of Organ Sharing database was queried from Jan 2016 to Dec 2021. Post‐transplant outcomes stratified by recipient MELD‐XI score (low <10.37, medium, 10.38–13.39, and high >13.4) was compared between patients with HT from HCV+ (N = 792) and patients with HT from HCV‐negative donors (N = 15,266). Results The median MELD‐XI score was comparable (HCV+, 12.1, vs. HCV‐negative, 11.8, p = .37). In the HCV+ group, donors were older (33 vs. 31 years, p < .001). Ischemic time of donor hearts (3.48 vs. 3.28 h, p < .001) and travel distance (250 vs. 157 miles, p < .001) were longer in HCV+ group. In the Kaplan Meier analysis with a median follow‐up of 750 days, survival was comparable between the two groups (2‐year survival, MELD‐XI Low: HCV+, 92.4 ± 3.6% vs. HCV‐negative, 91.1 ±.8%, p = .83, Medium: HCV+ 89.2 ± 4.3% vs. HCV‐negative, 88.2 ± 1.0%, p = .68, and High: HCV+, 84.9 ± 4.5% vs. HCV‐negative, 84.6 ± 1.1%, p = .75) In multivariate Cox hazard models, HCV donors were not associated with mortality in each MELD‐XI subgroup (Low: adjusted hazard ratio (aHR), 1.02, p = .94; Medium: aHR, .95, p = .81; and High: aHR, .93, p = .68). Conclusion Utilization of HCV+ hearts was not associated with an increased risk of adverse outcomes in recipients with an elevated MELD‐ XI score.
