Which option is NOT among the five most common direct targets for bypass grafting?

Explanation:
Direct targets for bypass grafting are the coronary arteries that supply the heart muscle. In typical CABG practice, the most commonly bypassed vessels include the left anterior descending artery, the right coronary artery, and the left circumflex system, with additional grafts often placed to diagonal branches and obtuse marginal branches. The superior mesenteric artery, by contrast, is a major visceral artery feeding the intestines and lies outside the coronary circulation. It is not a heart vessel and is not a usual target in CABG, which is why it is not among the common direct targets.
