ST segment depression when she was admitted to our catheter laboratory. Selective coronary angiography revealed the unexpanded stent embedded in the proximal part of the LCX (Figure 1).
Unexpanded stent in the LCX managed by compressing the inflated slipped stent against the vessel wall with another 3.0 mm x 15 mm bare metal stent

We decided to deploy an unexpanded stent in the LCX by a balloon catheter urgently, managed by compressing the inflated slipped stent against the vessel wall with another 3.0 mm x 15 mm BMS, without compromising coronary blood flow (Figure 2).

At the end of PCI, during crossing, the hydrophilic coated non-metallic tip of the guide wire (PT2, Boston Scientific Corporation) became detached and was fractured by stent striates (Figure 3).
The guidewire was pushed to the distal segment of the circumflex artery by a small, underinflated balloon catheter and it was isolated from the circulation by a 2.5 mm x 12 mm bare metal stent implanted over the wire

The guide wire was pushed to the distal segment of the LCX by a small, under-inflated balloon catheter and the retained guide wire tip was isolated from the circulation by implantation of a 2.5 mm x 12 mm BMS over the wire (Figure 4).
Optical coherence tomography demonstrating multiple thrombi in the struts and thrombosed area near the distal part of the stent

After 1 week optical coherence tomography (OCT) was performed to control the stent struts and OCT revealed multiple thrombi in the struts and thrombosed area near the distal part of the stent (Figure 5).
