OBJECTIVE: Allograft rejection is still an important cause of morbidity and mortality after heart transplantation (HTx). Many techniques in cardiac magnetic resonance imaging (CMR) were investigated to diagnose acute cellular rejection (ACR). However, there is not enough information about late @entity2287 enhancement (LGE) in the myocardium and ACR. METHODS: We prospectively analyzed our consecutive 41 heart transplant recipients who were admitted for routine endomyocardial biopsies. CMR was performed maximum 6 h before the scheduled endomyocardial biopsy. Correlation between LGE in the myocardium and ACR was investigated. RESULTS: Twenty-seven @entity1 showed no rejection, and nine of them had LGE in the myocardium. Fourteen @entity1 had LGE in the left ventricle (LV), and two @entity1 had LGE also in the right ventricle (RV). There was no correlation between LGE and ACR (p=0.879). There was no difference in the @entity1002 ( @entity1002 ), right ventricular fractional area change (RVFAC), and cardiac ischemic time between the groups (p=0.825, p=0.370, and p=0.419, respectively). LGE in the myocardium could be due to previous rejection episodes; therefore, all @entity1 were retrospectively searched for previous rejection grades and number of episodes. Thirty-eight of the 41 @entity1 had a history of one ACR episode, but none of them had a statistically significant correlation with LGE (for grade 1R, p=0.964 and grade 3R, p=1) There was also no correlation between number of rejection episodes history and LGE. CONCLUSION: LGE is not suitable to detect ACR in heart transplant @entity1 . LGE and the history of ACR have no correlation.

Diagnostic performance of late XXXX enhancement in the assessment of acute cellular rejection after heart transplantation.
