A: The ellipsoidally shaped finite element (FE) mesh of the left ventricle (LV) consists of 60 elements and is incorporated in a lumped parameter model of the circulation. AV, aortic valve; Inline graphic, arterial compliance; Inline graphic, venous compliance; MV, mitral valve; Inline graphic, arterial resistance; Inline graphic, peripheral resistance; Inline graphic, venous resistance; Inline graphic, zero-pressure arterial volume; Inline graphic, zero-pressure venous volume. B: Description of myofiber orientation vector in the unloaded state Inline graphic by helix angle Inline graphic and transverse angle Inline graphic using a local cardiac coordinate system {Inline graphic, Inline graphic, Inline graphic}.
