Concerns exist regarding orthotropic heart transplantation in hepatitis C virus (HCV) seropositive recipients. Thus, a national registry was accessed to evaluate early and late outcome in HCV seropositive recipients undergoing heart transplant. Retrospective analysis of the United Network for Organ Sharing registry (1991 to 2014) was performed to evaluate recipient profile and clinical outcome of patients with HCV seropositive (HCV +ve) and seronegative (HCV −ve). Adjusted results of early mortality and late survival were compared between cohorts. From 23,507 patients (mean age 52 years; 75% men), 481 (2%) were HCV +ve (mean age 52 years; 77% men). Annual proportion of HCV +ve recipients was comparable over the study period (range 1.3% to 2.7%; p = 0.2). The HCV +ve cohort had more African-American (22% vs 17%; p = 0.01), previous left ventricular assist device utilization (21% vs 14%; p <0.01) and more hepatitis B core Ag+ve recipients (17% vs 5%; p <0.01). However, both cohorts were comparable in terms of extracorporeal membrane oxygenator usage (p = 0.7), inotropic support (p = 0.2), intraaortic balloon pump (p = 0.7) support, serum creatinine (p = 0.7), and serum bilirubin (p = 0.7). Proportion of status 1A patients was similar (24% HCV + vs 21% HCV −); however, wait time for HCV +ve recipients were longer (mean 23 vs 19 days; p <0.01). Among donor variables, age (p = 0.8), hepatitis B status (p = 0.4), and Center for Diseases Control high-risk status (p = 0.9) were comparable in both cohorts. At a median follow-up of 4 years, 67% patients were alive, 28% died, and 1.1% were retransplanted (3.4% missing). Overall survival was worse in the HCV+ cohort (64.3% vs 72.9% and 43.2% vs 55% at 5 and 10 years; p <0.01), respectively. Late renal (odds ratio [OR] 1.2 [1 to 1.6]; p = 0.02) and liver dysfunction (odds ratio 4.5 [1.2 to 15.7]; p = 0.01) occurs more frequently in HCV +ve recipients. On adjusted analysis, HCV seropositivity is associated with poorer survival (hazard ratio for mortality 1.4 [1.1 to 1.6]; p <0.001). In conclusion, a small proportion of patients receiving a heart transplant in the United States have hepatitis C. Despite comparable preoperative hepatic function, hepatitis C seropositive recipients demonstrate poorer long-term survival.
