Segmentation by type categorizes grafts into autologous vein, arterial, and synthetic conduits, each with distinct clinical and economic profiles. Autologous saphenous vein grafts dominate the market, contributing approximately 55 % of total volume due to their wide availability, lower acquisition cost, and established long‑term outcomes, especially in multi‑vessel procedures. Arterial grafts—principally internal mammary and radial arteries—capture around 40 % of market value; despite higher procurement and handling expenses, they offer superior patency rates, prompting premium pricing and preferential use in high‑risk or younger cohorts. Synthetic grafts, such as expanded polytetrafluoroethylene (ePTFE), remain niche, comprising roughly 5 % of sales, limited to cases where autologous tissue is unsuitable. The distribution across these types determines overall market valuation, as arterial grafts command higher margins while vein grafts sustain volume, together defining the market taxonomy for Coronary Artery Bypass Grafts.
