Figure Lengend Snippet: Angiography and IVUS During PCI PCI before (A) and after (B) balloon angioplasty, mechanical thrombectomy, and IVUS-guided deployment of a second layer of Synergy XD (Everolimus DES with bioabsorbable polymer). (A) RAO/CAU pre-PCI of OM1 with visualization of old stent and thrombosis (red circle). (B) RAO/CAU post-PCI of OM1 with additional stent. IVUS showed areas of neo-atherosclerosis and neo-calcification. Although the original stent was well apposed, it appeared undersized (2.5-2.75 mm). (C) Pre-PCI IVUS showing minimal stent area of 1.61 mm 2 . (D) Post-PCI IVUS showing improved minimal stent area to 6.6 mm 2 . (E) IVUS shows proximal vessel reference diameter of 3.75 mm. (F) IVUS shows distal vessel reference diameter of 3.25 mm (G) Thrombus removed from OM1. CAU = caudal; DES = drug-eluting stent; IVUS = intravenous ultrasound; PCI = percutaneous coronary intervention; RAO = right anterior oblique.

Figure Lengend Snippet: Intravascular Ultrasound Findings The white arrow indicates the significant stenosis at the diagonal branch bifurcation via coronary angiography. The white triangle indicates the calcified plaque and the C-type calcified and residual thin plaque sign (C-CAT sign) observed by intravascular ultrasound. In addition, the reference vessel diameter was sufficient for 3.0 mm.

Article Snippet: After the 1.5-mm semicompliant balloon dilatation, an intravascular ultrasound (IVUS) (Opticross HD Plus 60MHz Coronary Imaging Catheter; Boston Scientific) was performed ( , ). shows the severe calcification at the distal bifurcation of the diagonal branch along with C-type calcified and residual thin plaque sign (C-CAT sign).
