The　Coronary　Artery　Bypass　Graft　(CABG)　yields　excellent　results　and　remains　the　modern　standard　of　care　for　treatment　of　occlusive　disease　in　the　cardiovascular　system.　However,　the　development　of　anastomotic　Intimal　Hyperplasia　(IH)　and　restenosis　can　compromise　the　medium-and-long　term　effects　of　the　CABG.　This　problem　can　be　correlated　with　the　geometric　configuration　and　hemodynamics　of　the　bypass　graft.　A　novel　geometric　configuration　was　proposed　for　the　CABG　with　two　symmetrically　implanted　grafts　for　the　purpose　of　improving　the　hemodynamics.　Physiological　blood　flows　in　two　models　of　bypass　grafts　were　simulated　using　numerical　methods.　One　model　was　for　the　conventional　bypass　configuration　with　a　single　graft　(1-way　model);　the　other　model　was　for　the　proposed　bypass　configuration　with　two　grafts　(2-way　model).　The　temporal　and　spatial　distributions　of　hemodynamics,　such　as　flow　patterns　and　Wall　Shear　Stress　(WSS)　in　the　vicinity　of　the　distal　anastomoses,　were　analyzed　and　compared.　Calculation　results　showed　that　the　2-way　model　possessed　favorable　hemodynamics　with　uniform　longitudinal　flow　patterns　and　WSS　distributions,　which　could　decrease　the　probability　of　restenosis　and　improve　the　effect　of　the　surgical　treatment.　Concerning　the　limitations　of　the　2-way　bypass　grafts,　it　is　necessary　to　perform　animal　experiments　to　verify　the　viability　of　this　novel　idea　for　the　CABG.
