Figure 1 Distribution and Percentage of Murality of Myocardial Infarctions in Transplant Coronary Artery Disease I to III
Infarct-typical (A, B) and -atypical (C to F) contrast-enhanced magnetic resonance imaging patterns. The red arrows point to the contrast-enhanced lesions.

Figure 2 Distribution and Percentage of Typical and Atypical Late Enhancement in TCAD I to III
(A) Comparison of the percentage of patients with infarct-typical contrast-enhanced magnetic resonance imaging (CE-MRI) and their distribution and murality of myocardial infarction in all 3 transplant coronary artery disease (TCAD) groups. Note the significant increase of infarct-typical lesions from TCAD I to III. The transmurality index was at least 25% to 50%. (B) Comparison of the percentage of patients with infarct-atypical CE-MRI and their distribution in all 3 TCAD groups. For infarct-atypical CE-MRI the presence of CE-MRI was evenly distributed among the groups. LE = late enhancement.

Figure 3 Distribution Patterns of Infarct-Typical and -Atypical CE-MRI
Distribution of all affected infarct-typical (A) and -atypical (B) contrast-enhanced magnetic resonance imaging (CE-MRI) segments related to the American Heart Association 17-segment model. Of infarct-typical lesions, 81% were accentuated in the mid-ventricular (segments VII to XII) and apical (XIII to XVII) segments. In contrast, 60% of infarct-atypical areas were accentuated at basal slices, predominantly lateral and inferior. *Segment XVII.
