Coronary Imaging System Detects Acute Stent Thrombosis With Lipid Core Plaque
December 27, 2010 – A case report in Circulation describes the association of stent thrombosis with lipid core plaque as detected by the LipiScan Coronary Imaging System. The LipiScan is the first and only FDA-approved system to provide a chemogram (map of lipid core plaque) within the imaged vessel via near-infrared (NIR) spectroscopy. The authors note that the case represents the first demonstration of acute stent thrombosis associated with disrupted lipid core plaque (LCP) as detected by NIR imaging with the LipiScan system.
The paper titled “Residual Thrombogenic Substrate After Rupture of a Lipid Rich Plaque – Possible Mechanism of Acute Stent Thrombosis? A Near-Infrared Spectroscopy Study” was published in Circulation (2010;122:2349-2350) under authors Sakhuja R., Suh W., Jaffer F. and Jang I.
"While stenting is an excellent means to treat flow restrictions caused by coronary plaques, it is in some cases complicated by thrombosis which may cause serious consequences,” said James E. Muller, M.D., founder and chief executive officer of InfraReDx. “This report by Sakhuja et al. describes the occurrence of thrombosis in a stent that ends in a lipid core plaque, a structure that contains substances known to be thrombogenic. This adds to the accumulating evidence that many complications of stenting – peristenting infarction, stent thrombosis and restenosis – are due not to features of the stent or stenting technique, but to the presence of a lipid core plaque at the stented site. We are pleased to make available the LipiScan IVUS Coronary Imaging System, which provides an easy and accurate method to detect lipid core plaque and thereby adds important information to the decision-making process."
The LipiScan IVUS Coronary Imaging System now combines both NIR (LipiScan) and intravascular ultrasound (IVUS) technologies. The IVUS feature provides an image of the plaque and coronary artery lumen, while the NIR feature provides rapid and accurate assessment of LCPs. Upon completion of a single catheter pullback, the LipiScan IVUS system is able to immediately generate and display a grayscale IVUS image of the coronary artery, along with a complete and co-registered chemogram within the imaged vessel.
