Overview
The coronary angiogram is fairly insensitive to the presence of lesion calcification, particularly the presence of deep vessel wall calcification. Intravascular ultrasound is much more sensitive in the assessment of vessel wall calcification. Conventional coronary angiography has limited sensitivity for the detection of smaller amounts of calcium, and has moderate sensitivity for the detection of extensive lesion calcium (sensitivity 60% and 85% for three- and four-quadrant calcium, respectively).[1] Calcification is often associated with older graft age, insulin–dependent diabetics, and smoking.[2]
Example
Shown below are an animated image and a static image depicting calcification in the right coronary artery. Encircled in yellow in the image on the right is the calcified lesion.
