Material Stress-Stretch curves, pressure conditions used in the paper and computational RV volume curve matching CMR-measured data. (a) Stress-Stretch curves from Mooney-Rivlin isotropic patch, scar and anisotropic RV tissue models used in this paper. Model parameter values (c2=0 for all models): Anisotropic RV model (out-layer given in plot): c1=5.746 kPa, c2=0, D1=1.479 kPa, D2=3.0, K1=23.413 kPa, K2=3.2; Scar: c1=19.227 kPa, c2=0, D1=19.227 kPa, D2=9.0; Patch: c1=38.454 KPa, c2=0, D1=38.454 kPa, D2=9.0; Tff: Stress in the fiber direction; Tcc: Stress in fiber circumferential direction. (b) Stress-Stretch curves from Mooney-Rivlin isotropic models for passive band materials. “1 Stiff”: c1=600 kPa, D1=300 kPa, D2=1.4; “5 Stiff”: c1=3,000 kPa, D1=1,500 kPa, D2=1.4; “10 Stiff”: c1=6,000 kPa, D1=3,000 kPa, D2=1.4; Curve fitting ME testing data: c1=1,510 kPa, D1= -221.9 kPa, D2=2.0; 900 kPa band: c1=900 kPa, D1= 0 kPa, D2= 0. (c) Imposed inner RV pressure; (d) Model validation: computational RV volume from the baseline no-band FSI model matching CMR-measured RV volume Data.
