Myocardial edema/late Gadolinium enhancement (LGE) and
myocarditis pattern
Myocardial edema based on T2 sequences was reported in 3 out of 5
studies [103–105]. Lake Louise criteria were satisfied in 4 out of
26 [103] and 8 out 10 patients[104]. Similarly, LGE was reported
in 5 studies[102–106]. Location and extent of LGE varied between
individual studies. Non -ischemic scar was observed in 20 out of 100
patients [102],in another study 8 patients had scar at RV insertion
(2 patients), 3 patchy involvement and 3 linear involvement [103]. 3
out of 10 patients [104] and 14 out of 26 patients [105] had
subepicardial LGE, 1 study reported that most LGE was observed at
inferior, and inferolateral basal and mid segments [105] and this
was confirmed in another study where 2 patients had infero-septal LGE
[106].
