Figure 1: A 86-year-old female with two-vessel coronary artery disease, total calcium score was 1278. The calcium score was 325 over the right coronary artery (RCA). (a) A computed tomographic angiogram shows mixed plaques over the middle third of RCA with 54% stenosis (white arrow). (b) Conventional coronary arteriogram confirms the moderate stenosis over the proximal as well as middle (arrow) third of RCA.
