Dislodgement of coronary stent due to rupture of stent balloon.

Rare stent complications, including dislodgement of stent, unexpanded stent, stent fracture and stent loss etc. can occur during percutaneous coronary interventions (PCI). We present a semi-expanded and dislodged stent due to rupture of stent balloon during primary PCI in this case report. An interventional cardiologist should be aware of the possibility of rare complications, such as in this case, and have enough experience and knowledge to handle them.
