HCV screening became possible in donors in 1991, eliminating the risk of iatrogenic infections. No formalized screening has been conducted for patients receiving non-screened blood, potentially leaving some with undetected HCV infection.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objectives:<\/jats:title>\n                    <jats:p>This study aimed to determine the prevalence of chronic HCV infection in this group of patients and offer treatment to those affected.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Design:<\/jats:title>\n                    <jats:p>Nationwide cross-sectional study.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Between 2020 and 2023, 1645 individuals who underwent pediatric heart surgery before 1992 in Denmark were identified. Participants were invited for HCV screening using anti-HCV-antibody and HCV-RNA tests. Patients testing positive for HCV were referred to direct-acting antiviral (DAA) treatment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Of 1645 patients identified, 571 consented to participate, and 246 completed HCV screening. Two individuals tested positive for chronic HCV infection, resulting in a prevalence of 0.8%. Both patients were asymptomatic for many years before treatment and successfully cleared the virus after DAA treatment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>The 0.8% prevalence of HCV in this cohort is higher than in the general Danish population although lower than in similar studies from the U.S. and Germany. This may reflect Denmark\u2019s practice of unpaid blood donation, reducing infection risks. Targeted screening for at-risk cohorts exposed to transfusions before 1992 could aid in HCV detection and treatment, potentially preventing long-term liver complications.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Registration:<\/jats:title>\n                    <jats:p>The study was approved by the Capital Region Ethics Board in Denmark (j.nr.
