Intravascular Imaging

This channel includes news and new technology innovations for intra-vascular ultrasound (IVUS) and optical coherence tomography (OCT) imaging systems used in the cath lab. These imaging modalities help with diagnostic decisions about how to treat atheroscolosis and help guide device placement and verification of stent apposition. The technology also is used to visualize in-stent restenosis.

bioresorbable stent, bioabsorbable stent, Absorb BVS, visualizing bioresorbable stents

A comparison of how the Abbott Absorb BVS appears with intravascular ultrasound (IVUS) on the left, and optical coherence tomography (OCT) of the right. The stent is difficult to visualize and sizing is critical, so both modalities can help in bioresorbable stent measurements and to confirm stent apposition. Left image from the Volcano IVUS system and the right image from St. Jude Medical's OCT system.
