65 years old male patient with history of dilated cardiomyopathy, multiple cardiovascular risk factors that was not able to perform MR due to old metal femoral stem. Calcified moderate stenosis was observed on mid-RCA (A), LAD (B) and moderate mixed plaque on proximal first marginal (C). Late iodine enhancement showed hyperenhancement of subendocradium in inferolateral wall (arrows, D) and papillary muscles (arrowheads, D), indicating necrosis/fibrosis/inflammation. H&E view of unstable atherosclerotic plaque (E), with necrotic core and spindle lipid deposits (arrows) and fibrous cap with diffuse inflammatory infiltrate (arrowheads).
