Abstract
A 69-year-old man underwent coronary angiography 7 years after coronary artery bypass. Saphenous vein graft spasm was observed during contrast injection, resulting in ventricular fibrillation. Angiography 6 years later showed graft patency. Vein graft spasm after coronary artery bypass grafting is rarely described. Further investigation is needed regarding incidence, mechanism, and clinical outcomes. (Level of Difficulty: Beginner.).
