We sought to evaluate the distribution and significance
of myocardial hyperintensity on T2-weighted imaging
(T2-HI) in patients with asymmetrical septal HCM (ASH).
On third of T2-HI was outside late gadolinium
enhancement, and the presence of T2-HI was significantly
related to unexpected syncope. T2-HI had longer T2
values than remote myocardium of ASH and normal
myocardium on T2 mapping. T2-weighted MRI should be
interpreted carefully to identify T2-HI related syncope
in ASH patients.
