Myocardial infarction at the infero-septal region of left ventricle (A-D). Inversion recovery mid ventricular short axis image (A) demonstrates subendocardial delayed enhancement at the infero-septal region of the left ventricle (white arrow) in the distribution of right coronary artery. Corresponding tagged image and strain analysis curves (B & D) demonstrate reduced E CC at the infarct region (blue curve 1) compared to lateral wall (red curve 2) and adjacent non enhanced myocardium (green curve 3). Color coding (C) of tagged image aids visual assessment of regional dysfunction (dysfunctional infarcted myocardium in green). See additional file 3: Movie 3 for the original data used.
