Referral for coronary CT as part of a preoperative evaluation in a 60-year-old man with a history of aortic valve replacement and complete heart block after dual-chamber pacemaker placement. (a) Curved multiplanar reformatted CCTA image of the LAD coronary artery shows a moderate (50%–69%) coronary stenosis (arrow) within the proximal LAD. (b) FFR CT image shows an FFR value of 0.72 distal to the moderate stenosis in the proximal LAD, compatible with a functionally significant coronary stenosis.
