The following angiograms show the results of a double coronary artery bypass procedure performed in an adult sheep. In this case, two 5.5 mm outside diameter saphenous veins were used as the bypass conduits. The control graft, a bare saphenous vein, was sewn from the descending aorta to the 2nd diagonal branch of the left anterior descending coronary artery. The test graft, a saphenous vein fitted with a 3.5 mm inside diameter eSVS Mesh, was sewn from the descending aorta to the 1st obtuse marginal branch of the left circumflex artery.

At implant, both grafts are patent with regular lumens and fair contrast runoff. At 30 days post implant, the graft fitted with the eSVS Mesh has a regular lumen and exhibits excellent contrast runoff while the control graft shows significant remodeling, an irregular lumen and fair to poor contrast runoff. At 60 days post implant, the eSVS Mesh graft continues to show a regular lumen with excellent contrast runoff while the control graft continues to remodel and exhibit poor contrast runoff. At 90 days post implant, the eSVS Mesh graft continues to show excellent contrast runoff, while the control graft is now completely occluded.
