(a) Followup coronary angiography at 39 months (RAO caudal view). Arrows 1, 2, and 3 indicate corresponding cross-sections of the OCT findings in Figures (d)– (f). (b) Followup coronary angiography at 39 months (AP cranial view). (c) Control coronary angiography before PCI two months after the diagnostic coronary angiography (AP cranial view). There was no progression of stenosis in the proximal LAD during the two months. (d) OCT findings before PCI in the proximal stenosis (arrow 1 in Figure 1(a)). (e) OCT findings before PCI in the distal stenosis (arrow 3 in Figure 1(a)). (f) OCT findings before PCI in the distal stenosis (arrow 2 in Figure 1(a)). (g) IVUS findings before PCI. RAO: right anterior oblique view; AP: anteroposterior; PCI: percutaneous coronary intervention; OCT: optical coherence tomography; IVUS: intravascular tomography; LAD: left anterior descending coronary artery.
