Methylergonovine-induced spasm of saphenous vein coronary bypass graft.
A case of repeated methylergonovine-induced spasm of a saphenous vein bypass graft in a 56-year-old man is presented. Prior to the operation, spasm was induced by methylergonovine in the stenosed right coronary artery. Six months after the operation, coronary angiographic studies showed induced spasm of the right coronary graft but no spasm in native vessels nor in the other graft to the left anterior descending coronary artery.
