Insights
A dislodged drug-eluting coronary stent during intervention was successfully repositioned using balloon-assisted deployment. This technique offers a viable solution for managing dislodged coronary stents in complex arterial anatomy.
Area of Science:
- Interventional Cardiology
- Cardiovascular Surgery
Background:
- Coronary artery interventions, particularly in calcified and tortuous vessels, carry risks.
- Stent dislodgement is a rare but significant complication during percutaneous coronary intervention.
Observation:
- A drug-eluting stent became dislodged in the osteoproximal segment of a calcified and tortuous left circumflex coronary artery (LCX) during intervention.
- The dislodged stent was successfully rewired and progressively dilated with multiple balloons.
Findings:
- A larger, balloon-mounted stent was advanced and deployed across the coronary lesion after the dislodged stent was prepared.
- The procedure resulted in successful restoration of distal thrombolysis in myocardial infarction (TIMI) III flow with favorable angiographic outcomes.
Implications:
- Balloon-assisted deployment of a dislodged stent is a feasible technique for managing proximal stent displacement.
- This approach can prevent more complex interventions and improve patient outcomes in challenging coronary anatomies.
Abstract:
We report a first and interesting case of balloon-assisted deployment of a dislodged coronary stent. While performing a calcified left circumflex coronary artery (LCX) intervention, the drug-eluting coronary stent was dislodged in the osteoproximal segment of the calcified and tortuous LCX. The dislodged stent was rewired, progressively dilated with multiple balloons and, finally, a larger, balloon-mounted stent was pushed forward, positioned across the coronary lesion and deployed, resulting in distal thrombolysis in myocardial infarction (TIMI) III flow with good angiographic results. Rewiring the dislodged stent with subsequent balloon-assisted deployment in the lesion can be a solution for a dislodged coronary stent in the proximal vessel.
