a 56-year-old man with a two year history of chronic stable angina underwent elective coronary artery bypass grafting (cabg) due to angiographic report of three vessel disease and tight stenosis at proximal part of left anterior descending artery (lad). while harvesting of radial artery (ra), the distal half of radial artery was found to bifurcate to two parallel branches with equal size. we us...

In this paper, an analytical formula to calculate the radial stiffness of groove elastic support is presented. The influence of structure parameters on radial stiffness and homogeneity of radial stiffness is investigated as well. The accuracy and calculating speed of the analysis formula are compared to that of finite element method (FEM). Findings are as following: The calculating speed of ana...
