Hepatitis C virus positive (HCV+) organ donors offer a viable strategy for expansion of the heart donor pool without an increased risk of recipient mortality. Cardiac magnetic resonance imaging (CMR) is an effective tool for graft surveillance in heart transplant (HT) recipients. However, there are no data comparing CMR findings in HT recipients based on donor HCV status. The aim of this propensity score matched case-control study was to evaluate baseline CMR characteristics of HCV+ HT recipients and HCV- HT recipients, as well as compare cardiac allograft structure, function, performance, and tissue characterization between groups. CMR normative values did not differ between groups in matched analysis. There were no significant differences in CMR-derived biventricular function, strain, late gadolinium enhancement, or myocardial tissue characteristics by parametric mapping. This study suggests CMR can be a valuable tool for surveillance in HCV+ HT patients, and abnormalities on imaging should not be attributed to HCV infection.
丙型肝炎病毒阳性(HCV+)器官供体为扩大心脏供体库提供了一种可行策略,且不会增加受体死亡风险。心脏磁共振成像(CMR)是心脏移植(HT)受者移植物监测的有效工具。然而,尚无基于供体HCV状态比较HT受者CMR检查结果的数据。这项倾向评分匹配的病例对照研究旨在评估HCV+ HT受者和HCV- HT受者的基线CMR特征,并比较两组之间心脏同种异体移植物的结构、功能、性能和组织特征。匹配分析中,两组之间的CMR规范值没有差异。通过参数映射,CMR得出的双心室功能、应变、钆延迟增强或心肌组织特征没有显著差异。这项研究表明,CMR可以成为HCV+ HT患者监测的有价值工具,影像学上的异常不应归因于HCV感染。
