The only non-perfectly patent arterial conduit. The only patent, but diseased arterial conduit was a radial artery to second marginal, illustrated by arrows. However, it was noted to be diseased at the time of surgery 11 years prior and it is not known if there has been any progression postoperatively. The native coronary artery has severe disease and was noted to be diseased at the time of surgery. https://s3.amazonaws.com/igraft/3Vangio/PreopDiseasedRA.mp4. From the operation report: “The left radial artery was exposed but on harvesting was found to be extensively calcified and not useable. The right radial artery was harvested; this was a 2.2 mm artery with at least moderate medial wall calcification”
