When you have a complex decision to make, knowledge is power. IVUS helps you see what FFR can’t, providing at least 10 different pieces of information on the target lesion compared to FFR’s one. You’ll know everything from lesion significance and stent expansion to percent stenosis and stent apposition. And the more you know, the more you can do for your patient. For IVUS solutions that support clinically sound decisions, look to Boston Scientific to see what matters.

| Lesion Significance | X | X |
| Stent Expansion | X | |

| Stent Diameter Sizing | X | |
| Stent Length Sizing | X | |
| Plaque Burden | X | |
| Plaque Tissue Type | X | |
| % Stenosis | X | |
| Stent Placement | X | |
| Lesion Morphology | X |
The study concluded that using IVUS during DES implantation has the potential to influence treatment strategy and affect both DES thrombosis and the need for repeat procedures.

As reported by Costantini, patients in the IVUS group had the following lower rates compared to those in the non-IVUS group:
