Figure 6. Composite (n = 10) MRI-based Multiparametric Strain Z-Score Color Contour Left Ventricular 3D Mapping.
Multiparametric strain Z-scores from each of 15,300 points for each of ten dilated cardiomyopathy patients were averaged together to create a single representation of the composite regional and transmural myocardial contractile function that can be anticipated in patients in this heart failure subgroup. The regional heterogeneity of contractile dysfunction relative to the expected regional norm, including the predominant impairment of the ventricular septum, is demonstrated in this composite color contour map representing the entire group of non-ischemic, non-valvular dilated cardiomyopathy patients. AS = anteroseptal; A = anterior; AL = anterolateral; PL = posterolateral; P = posterior; PS = posteroseptal.
