Description	The aim of this study is to describe mechanical response of coronary artery bypass graft (CABG). Attention was paid to sensitivity of a model to small torsions superimposed to an inflation and extension of an artery. The inflation-extension test was performed. A presence of torsions was proved via displacements analysis based on digital image correlation. CABG was modeled as nonlinearly hyperelastic, anisotropic and incompressible material with thin-walled cylindrical geometry. A strain energy function based on limiting fiber extensibility was used. Estimation of material parameters led to good agreement between the model and observations. It was concluded that the model is insensitive to small torsions superimposed to inflation-extension of the artery.
