CMR images from a 63 years old male who presented with an anterior ST elevation myocardial infarction. Early after reperfusion, T2W images demonstrated increased signal intensity (myocardial oedema) in the interventricular septum. However, the extent of oedema gradually decreased and by 3 months was undetectable. LGE images from the same patient demonstrated almost transmural infarction in the septum. MVO is present at ‘day 2’ and ‘1 week’ after reperfusion (dark core within the infarct zone) but is undetectable at ‘1 month’. The infarct size decreased during the first month after reperfusion.
