High Amount of Lipid Rich Necrotic Core Lesion Identified by Pre-interventional Intravascular Ultrasound (IVUS) is Associated With High Rate of Delayed Hyper-enhancement as Detected by Contrast-enhanced Cardiac Magnetic Resonance Imaging
The purpose of this study is to evaluate whether some features of plaques in coronary
arteries predispose the heart muscle to injuries during angioplasty in patients with a
narrowing in at least one of the arteries that may need a stent placed during a heart
catheterization. Participants undergo a cardiovascular magnetic resonance imaging (MRI)
study before the heart catheterization to look for scarring in the heart muscle. During the
heart catheterization, participants undergo an intravascular ultrasound (IVUS) exam to look
at the make-up of the plaques before the stent placement and the investigators will measure
the pressures in the arteries to look at how severe the blockage is. Within 30 days after
the heart catheterization, participants will have a second MRI done to look for any new scar
in the heart muscle.
