We present a case of an accidentally crushed stent due to an unnoticed passage of a guidewire through a lateral stent strut with subsequent stent compression after balloon dilatation, during a planned percutaneous coronary intervention on the left main. The crushed stent segment was reconstructed with step-by-step balloon dilation, guided by intrav...

Context 1
... patient remained stable with normal flow in the LM and LAD. Guided by IVUS, a second wire (Sion, Asahi Intecc, Japan), with a 30 • bend in its 1 mm distal tip, was introduced within the crushed stent segment ( Figure 6). Once the guidewire was positioned inside the stent, progressive dilations with small (1.5 mm) to large (4 mm) balloons were performed until the stent regained its cylindrical shape (Figure 7). ...

Rationale
Stent fracture has received increased concern as it may be an important risk factor for late stent failure, intravascular ultrasound (IVUS) is always recommended to confirm the diagnosis of stent fracture. StentBoost can detect stent fractures more easily due to the enhanced stent strut visibility, compared with coronary angiography (CAG)...
