  1. The four PC modes (M1-M4) represent the highest percentage of shape variance (% Var), with a total of 66% at ES and 71% at ED, within the asymptomatic population as compared to other shape modes derived from PCA (not shown). The shape characteristic represented by each mode is noted. PC with the largest absolute score is highlighted in bold for each model. Patient 3 has not undergone stent implantation. Patients 4 and 5 have not undergone 2-year follow-up CMR. Corresponding models and PC scores for Patients 3-5 are not available.
