Summary
StentBoost® (SB) enhances stent visualization during percutaneous coronary interventions (PCI). This technique identified approximately 20% of underdeployed stents missed by coronary angiography, improving PCI outcomes.
Area of Science:
- Cardiology
- Medical Imaging
- Interventional Cardiology
Background:
- Stent underdeployment and malapposition in PCI can lead to thrombosis and restenosis.
- Coronary angiography has limited accuracy for assessing stent deployment.
- Advanced imaging like intravascular ultrasound is underutilized in routine PCI.
Purpose of the Study:
- To assess the added value of StentBoost® (SB) for stent deployment evaluation.
- To determine SB's role in optimizing percutaneous coronary interventions (PCI).
Main Methods:
- Retrospective analysis of 260 coronary lesions treated with stenting and assessed by SB.
- Comparison of SB findings with coronary angiography (CA) by two interventional cardiologists.
- Evaluation of 275 implanted stents, including drug-eluting stents (DES).
Main Results:
- SB detected underdeployment in 18% of cases where CA showed good results.
- Postdilatation based on SB improved deployment in 89% of these cases.
- SB's additional benefit was notable for left main lesions and DES.
Conclusions:
- StentBoost® is valuable in current PCI practice.
- SB identified significant underdeployment missed by CA, enabling optimization.
- Ad hoc postdilatation guided by SB effectively improved PCI outcomes.
