|Condition or disease||Intervention/treatment||Phase|
|Coronary Artery Disease||Device: InfraReDx Lipiscan IVUS||Phase 4|
The aims of this study are to:
- Test the ability of the new NIRS IVUS system to detect lipid pool
- Evaluate the accuracy of the NIRS IVUS system for localization of lipide rich plaque: superficial vs deep
- Improve diagnostic accuracy of OCT for detection of lipid using information from NIRS IVUS

Experimental: Coronary stenting with OCT, NIRS/IVUS
All subjects will have Near Infrared Spectroscopy/Intravascular Ultrasound Imaging performed.
Device: InfraReDx Lipiscan IVUS
Near Infrared Spectroscopy/Intravascular Ultrasound will be performed following OCT imaging.
- Detection of Lipid Rich Plaque by Near Infrared Spectroscopy (NIRS) Intravascular Ultrasound (IVUS) [ Time Frame: Measured one point in time during cardiac catheterization ]Subjects are presenting for their clinically-indicated cardiac catheterization. NIRS/IVUS imaging will be done at the time of catheterization.
- Differences in NIRS Parameters Between Deep and Superficial Lipid Assessed by Optical Coherence Tomography (OCT). [ Time Frame: Measured at the time of cardiac catheterization ]Subjects are presenting for their clinically-indicated cardiac catheterization. NIRS/IVUS imaging will be done at the time of catheterization. Plaques were divided depending on depth of lipid by OCT (cut off value 130 um).
