  FIG. 1 (A) Inserted 6 French sheath via left snuffbox approach. (B) Urgent CAG demonstrating the severe stenosis in the left main bifurcation site (arrow, left) and post-PCI CAG demonstrating successful stenting with POT of the left main bifurcation site (right). (C) IVUS imaging demonstrating MLA of 2.3 mm2 and plaque burden of 86.5%. (D, E) Pre-PCI IVUS demonstrating distal and proximal reference vessel diameter of 3.95 mm and 5.45 mm, respectively. (F) Post-PCI IVUS demonstrating MSA of 8.0 mm2. (G) IVUS cross-section demonstrating stent area of 15.7 mm2 and good strut apposition (arrowheads) in the left main bifurcation site (arrow, wire in LC×). (H) Post-PCI IVUS demonstrating DES overexpansion and stent diameter of 4.9 and 5.4 mm at maximal stent area site. CAG: coronary angiography, DES: drug-eluting stent, EES: everolimus-eluting stent, IVUS: intravascular ultrasound, MLA: minimal lumen area, LCx: left circumflex artery, PCI: percutaneous coronary intervention, POT: proximal optimization technique.
