Shown are inflated volume Vinfl; contracted volume Vcont; time of maximal contraction tcont; inflation fraction (IF), ejection fraction (EF). Spearman-ρ values for correlation: inverse of wall thickness (Wt), inverse of curvature (C), inverse of (thickness × curvature) (WtC) each versus stress at inflation (ρinfl) and contraction (ρcont). For all models the initial volume was 51 mL since they are all based on the patient case 3 from Table 1.
