Measurement of left ventricular (LV) myocardial thickness on short axis cine images at the end of diastole. First, the basal (a), mid-ventricular (b) and apical (c) level was defined. Second, all 16 segments (S1-S16) of the American Heart Association segmentation model were determined. And third, myocardial thickness was measured three times for each segment shown for segments S2, S8 and S14 (white arrows). S, segment
