  • Figure 1 (A) Coronary angiography revealed a large thrombotic aneurysmal change in the previous stent site with a true-bifurcation lesion (Medina 0, 1, 1) on the left anterior descending artery. A white arrow indicates an aneurysm originating at the proximal edge of the previous stent. (B) Intravascular ultrasound revealed a large aneurysm at the previous stent site (white arrows). (C) A stent-graft was successfully implanted without complication and the flow to aneurysm portion was decreased. (D) The true-bifurcation lesion was treated with a dedicated bifurcation stent. (E) Final angiography revealed successful results. (F) Stent patency was confirmed at the 4-month follow-up coronary computed tomography. Complete regression of the previous large aneurysm was shown at (G) 2-year follow-up, and (H) 7-year follow-up coronary angiography.
