Angiograms show a silhouette of the artery. IVUS and OCT show the inside wall in detail — plaque, calcium, and how well a stent is expanded.
Benefits of imaging-guided PCI
- More accurate vessel sizing
- Detection of under-expanded or malapposed stents
- Better understanding of calcium before modification
- Fewer surprises after the procedure
Why this matters in complex cases
In CTO and calcified disease, what you cannot see can compromise results. Precision imaging helps ensure the stent you receive is optimised for lasting benefit — not just for a good-looking angiogram at the end of the case.
