The dramatic 3D IVUS imaging demonstrating a dislodged coronary stent.

Area of Science:

• Cardiovascular medicine
• Medical imaging
• Interventional cardiology

Background:

• Coronary artery disease necessitates interventions like stenting.
• Complex coronary anatomy poses challenges during stent deployment.
• Accurate visualization is crucial for managing procedural complications.

Purpose of the Study:

• To demonstrate the utility of 3D intravascular ultrasound (IVUS) in a case of dislodged stent.
• To highlight the capability of 3D IVUS for precise localization of lost intracoronary devices.

Main Methods:

• A 78-year-old female patient with typical exertional chest pain underwent coronary angiography.
• Severe stenoses in the left anterior descending coronary artery (LAD) and diagonal branch ostium were identified.
• A stent was deployed in the LAD, followed by an attempt to stent the diagonal branch, resulting in stent dislodgement.
• Three-dimensional intravascular ultrasound (3D IVUS) was utilized to visualize the dislodged stent.

Main Results:

• Coronary angiography revealed significant stenoses requiring intervention.
• A stent dislodged from its balloon platform during deployment in the diagonal branch.
• Dramatic 3D IVUS images clearly depicted the dislodged stent within the coronary vasculature.

Conclusions:

• 3D IVUS provides exceptional visualization of dislodged stents.
• This imaging modality facilitates precise location and assessment of lost stents.
• 3D IVUS can be a valuable tool in managing complex interventional cardiology complications.
