Procedural outcomes with use of the flash ostial system in aorto-coronary ostial lesions.

Background: The Flash Ostial system (Ostial Corporation, Sunnyvale, CA) was designed to optimize implantation of aorto-ostial coronary stents by flaring the proximal stent struts against the aortic wall.

Methods: We retrospectively reviewed the medical record, angiograms, and intravascular ultrasound images of 22 aorto-ostial percutaneous coronary interventions performed at our institution between March and September 2015. The Flash Ostial system was used in 13 cases (59%).

Association of coronary lipid core plaque with intrastent thrombus formation: a near-infrared spectroscopy and optical coherence tomography study.

Background: Optical coherence tomography (OCT) and near-infrared spectroscopy (NIRS) allow assessment of the anatomy (OCT) and composition (NIRS) of coronary lesions. We sought to examine the association between pre-stenting lipid core plaque (LCP), as assessed by NIRS and post-stenting thrombus formation, as assessed by OCT.

Methods: We reviewed the angiograms of nine patients who underwent coronary stenting in association with NIRS and OCT imaging.
