IVUS interpretation

Clinical evidence

Advanced imaging

Peripheral IVUS

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.

ADAPT-DES

PCI strategy changed 74% of the time²

The ADAPT-DES study reported that IVUS guidance was associated with a change in PCI strategy 74% of the time.² Most often, the impact was a larger size of stent or balloon followed by 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 MACE³

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).³

reduction in MACE associated with IVUS guidance

Relationship between IVUS use and MACE (definite/probable ST, cardiac death, MI) within 2 years

ULTIMATE all-comers RCT

Intravascular ultrasound-guided versus angiography-guided implantation of drug-eluting stent in all-comers.⁴

“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.”

Primary endpoint based on patient-level comparison

Primary endpoint on patient level comparison

Increased rate of TVF* at one year without IVUS-guided PCI.

*(TVF categorized as cardiac death, target vessel MI and clinically driven TVR)

Target vessel failure increased by 175% when pre-specified IVUS criteria for optimal PCI was not achieved

Primary endpoint for patients who meet/didn’t meet IVUS criteria

Primary endpoint for patients on IVUS criteria

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.

Samsung registry

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.¹⁰

Clinical outcomes

Economic impact of IVUS

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.¹¹

• The analysis modeled incremental cost effectiveness based on DRG tariffs and outcomes data from the Ahn meta-analysis.

• Most data points are in the south-east quadrant indicating better outcomes and lower costs with IVUS-guidance versus angiography alone.
• Cost savings increased in patients with diabetes, renal insufficiency, or ACS and were associated with less MI and revascularization.
