  FIG. 1 Last coronary angiography (CAG) at 8 years ago revealed critical in-stent restenosis (ISR) in right coronary artery (panel A, arrow head). It was successfully treated with an additional drugeluting stent (DES, panel B). CAG revealed ISR at the stented site (panel C, arrow). However, the fluoroscopic image (panel D, dotted line) and Stent-Boost® enhanced fluoroscopic image (panel E) revealed complete transection of the DESs overlapped site.

• 

  FIG. 2 Intravascular ultrasound confirmed complete stent fracture in drug-eluting stents (DES)s overlapped site (A, middle image), and previous DES overlapping in distal to stent fracture site (A, bottom image). There was no significant in-stent restenosis (ISR) in previously implanted Taxus® proximal to the stent fracture site (A, top image). Final coronary angiography after 3.5×18 mm Xience Sierra® implantation for ISR site showed good distal flow without significant residual stenosis (B). MLA: minimal lumen area, MSA: minimal stent area.
