Embolised stent into the circumflex coronary artery during percutaneous coronary intervention

Area of Science:

• Cardiovascular medicine
• Interventional cardiology
• Medical device technology

Background:

• Coronary stents are crucial for treating blocked arteries.
• Newer stent generations aim for improved deliverability and efficacy.
• Stent embolisation before deployment is a rare but serious complication.

Observation:

• A rare complication involving dislodgement and embolisation of a new generation coronary stent prior to full deployment was observed.
• The embolised stent became lodged within the coronary artery lumen.

Findings:

• Complete withdrawal of the embolised stent was not feasible.
• A technique involving balloon angioplasty over a parallel wire was employed to crush the stent against the arterial wall.
• This maneuver successfully repositioned the stent, mitigating acute risks.

Implications:

• This case demonstrates a viable salvage technique for managing unreconstructable stent embolisation.
• The findings highlight the importance of preparedness for rare device-related complications in interventional cardiology.
• Further research may explore optimal strategies for managing similar embolic events with novel stent designs.
