Figure 1 Percentage of segments with normal wall motion (WM) at the sixth month (wall thickening >2 mm) depending on the five-level comprehensive score. Viability indexes: wall thickness >5.5 mm, normal perfusion, wall thickening during low-dose dobutamine >2 mm, and transmural extent of necrosis <50%. In Level 2, wall thickness >5.5 mm and/or normal perfusion should be present. – = index absent; + = index present; +/– = index may be present or absent.

Figure 2 Cardiovascular magnetic resonance imaging allowed a simultaneous assessment of four viability indexes in the same session. (Upper panels) Using cine-images, end-diastolic wall thickness and wall thickening during low-dose dobutamine infusion were quantified. (Lower panels) Example of a patient with an anterior infarction showing a perfusion defect (left) and transmural necrosis (right) in the anterior territory.
