a Pressure–volume (PV) loop of healthy LV geometry when the diastolic sheetlet angle (SA) was 18 ${}^{\circ }$, myocardial contractility $T_{\max }$ was 150 kPa and global myocardial stiffness C was 100 Pa, b PV loop of HCM LV geometry when the diastolic SA was 48 ${}^{\circ }$, and $T_{\max }$ and C were the same as in the healthy geometry, or when $T_{\max }$ was reduced and C was increased, c PV loop of DCM LV geometry when the diastolic SA was 18 ${}^{\circ }$, and $T_{\max }$ and C were the same as in the healthy geometry, or when $T_{\max }$ was reduced and C was increased. All the transverse angle and shear stiffness $B_{\mathit{n}\mathit{s}}$ were 10 ${}^{\circ }$ and 15.0, other parameters are fixed as Tables 4 and Table 5
