Get inside with IVUS.
From vessel size to plaque morphology and geometry to guidewire position, IVUS gets you inside the vessel to acquire precise information not apparent from angiography alone. Allowing you to consistently see clearly and treat optimally.

Get inside with IVUS.
From vessel size to plaque morphology and geometry to guidewire position, IVUS gets you inside the vessel to acquire precise information not apparent from angiography alone. Allowing you to consistently see clearly and treat optimally.
To develop a precise treatment plan, angiography alone is not enough.
Angiography can reveal luminal characteristics, show blood flow, and visualize the location of treatment devices. But because it delivers a 2D, outside view of the vessel, angiography has limitations when it comes to determining accurate vessel size, identifying plaque morphology, and understanding the extent of atherosclerosis.
Is this a dissection, calcium, thrombus, or stenosis?

The four pillars of IVUS
IVUS technical characteristics
IVUS has the potential to change treatment plans and improve outcomes.
A host of clinical studies have revealed the advantages of using IVUS in conjunction with angiography.
Study
Compare outcomes with IVUS and angiography-guided PVIs1
Key finding
Lower risk of periprocedural adverse events and vascular complications in the IVUS group
Study
Visual estimate of vessel diameter by angiography vs IVUS2
Key finding
Measurements estimated from the angiographic images were significantly smaller than those obtained by IVUS
Study
One-year outcomes in femoropopliteal in-stent restenosis using directional atherectomy with IVUS-guidance vs atherectomy guided by angiography3
Key finding
Clinically-driven target level revascularization was lower in IVUS-guided procedures vs angiography-guided procedures (p=0.03)
Study
Correlation of IVUS with angiographic findings demonstrating femoropopliteal arterial dissection post atherectomy4
Key finding
IVUS identified 46 post-atherectomy dissections while angiography identified 8 (p<0.01)
Study
Validation of 3 angiographic scoring systems for PAD with IVUS5
Key finding
IVUS detected calcium in 93.6% of lesions; angiography detected calcium in 55.3% of lesions (p<0.001)
Study
IVUS-assisted vs unassisted nitinol stenting for TASC II (A-C) femoropopliteal lesions6
Key finding
Analysis of 234 propensity matched pairs demonstrated higher primary patency; secondary patency; freedom from reintervention; freedom from any adverse limb event; and event free survival in IVUS-assisted procedures
