Figure 3: This picture demonstrates the porcine heart (a) and cross-sectional slice (b). The dark area stained with Evans Blue indicates nonischemic territory, and the red area stained with TTC is the area at risk for ischemia (TTC-positive). In (b), the white area is the infarcted (necrotic) myocardium (TTC-negative). The schema explains what the stained colors and territories indicate (c). LAD: left anterior descending artery.
