IVUS guidance
benefits patients
IVUS imaging helps you decide, guide and confirm the right interventional treatment for each patient. IVUS-guided strategies are backed by various studies and The Society for Cardiac Angiography and Interventions (SCAI) expert consensus statement states that IVUS is “definitely beneficial”.1 Explore the various studies below to learn more.
ULTIMATE RCT 3-year outcome data
Intravascular ultrasound-guided versus angiography-guided implantation of drug-eluting stent in all-comers.6
“Routine IVUS-guided DES implantation is associated with fewer major adverse cardiac events (MACE) compared with angiography guidance for patients with individual lesion subset. However, prior to the ULTIMATE trial the beneficiary effect on MACE outcome from IVUS-guidance over angiography-guidance in all-comers who undergo DES implantation remained understudied.”
— Zhang J et al 6
Compared to angiography-guided PCI alone, in all comer patients, ULTIMATE shows that IVUS-guided PCI significantly reduces clinically driven Target Lesion Revascularization (TLR). This benefit was sustained over three years. Only 1.6% TVF* at 12 months and 4.2% TVF at 3 years when optimal IVUS-guided PCI criteria was met.
Primary endpoint based on patient-level comparison
54% reduced rate of TVF at 3-years when optimal IVUS-guided PCI criteria was met.
Imaging standardization with 3 IVUS defined
criteria to achieve optimal PCI
Plaque burden at the 5-mm proximal or distal to the stent edge <50%.
Expansion satisfactory: Minimal lumen CSA in stented segment >5mm2, or 90% of distal reference lumen CSA.
No edge dissection involving media with length >3mm.
IVUS-XPL 5-year outcomes
Reduction in MACE2
The IVUS-XPL study was a prospective, multi-center, randomized trial resulting in:
ADAPT-DES
PCI strategy changed 74% of the time3
The ADAPT-DES study reported that IVUS guidance was associated with a change in PCI strategy 74% of the time.3 Most often, the impact was a larger sized stent or balloon, higher inflation pressures or post-dilation. Furthermore, the study reported that larger stent areas resulted in cases where both pre-and post-PCI IVUS were performed compared to when only post-PCI IVUS was performed.
34% reduction in MACE5
The ADAPT-DES study reported that IVUS guidance was associated with a 34% reduction in major adverse cardiac events (MACE) at 2 years (4.9% vs 7.4%, p < 0.001).5

Samsung registry
43% lower risk of cardiac death12
6,005 patients who had at least one complex lesion undergoing PCI with drug-eluting stents were enrolled in a prospective institutional registry. IVUS guidance was used on 1,674 enrolled patients. IVUS-guided PCI was associated with 43% lower risk of cardiac death during 64 months of median follow-up compared with angiography-guided PCI.12
Clinical outcomes
Economic impact of IVUS
IVUS-guided PCI with DES is a dominant treatment option vs. angiography13
An analysis of IVUS-guided PCI and angiography-guided PCI from an Italian healthcare payer perspective found that IVUS-guided PCI with DES is a dominant treatment option compared to angiography-guided PCI with DES.13 • Most data points are in the south-east quadrant indicating better outcomes and lower costs with IVUS-guidance versus angiography alone.
• The analysis modeled incremental cost effectiveness based on DRG tariffs and outcomes data from the Ahn meta-analysis.
• Cost savings increased in patients with diabetes, renal insufficiency, or ACS and were associated with less MI and revascularization.
