Endocardial longitudinal strain study of a patient with significant coronary artery disease. The automatic strain analysis in a patient with angina and significant left anterior descending (LAD) artery stenosis. The apical four-chamber view showes reduced colour coded subendocardial strain values segments supplied by the left LAD artery. Colour-coding from yellow to green indicates strain from +30% to -30%. Yellow = normal strain. Brown = areas with reduced strain. On the right strain curves for the 6 subendocardial segments are presented. The white arrow shows reduced strain values of – 14% in the curves representing the segments supplied by the LAD artery. AL = apicolateral; AS = apicoseptal; BL = basolateral; BS = basoseptal; ML = midlateral; MS = midseptal.
