There are 2 arms to this study. Arm 1: Participants undergoing coronary angiography for stable or acute coronary disease presentations and eligible for percutaneous coronary intervention (PCI) will be imaged with OCT-NIRAF at baseline and with CCTA 12 months apart to demonstrate that: 1. NIRAF coronary artery signal level (patient, artery, lesion basis) is correlated with the severity of coronary artery disease. 2. NIRAF coronary artery signal level is a predictor of plaque progression on a per participant, per artery, or per lesion basis. Arm 2: Participants undergoing coronary angiography for stable or acute coronary disease presentations and eligible for percutaneous coronary intervention (PCI) will be imaged with OCT-NIRAF following injection of LUMISIGHT. The primary objective is to assess the feasibility of intravascular detection and spatial localization of LUMISIGHT during routine coronary imaging.
Arm 1: This study will provide preliminary data on the clinical value of intracoronary OCT-NIRAF imaging in participants undergoing invasive coronary angiography in the cardiac catheterization laboratory. This is a single site, prospective feasibility study where 40 study subjects undergoing coronary angiography for stable or acute coronary disease presentations and eligible for percutaneous coronary intervention (PCI) will undergo intravascular imaging, including standard-of-care IVUS and then OCT-NIRAF pullback imaging conducted during an iodinated contrast flush. Patients will be consented…

Subjects will be imaged with OCT-NIRAF research catheter during their clinically indicated coronary angiogram. In addition, the subject will also receive two Coronary Computed Tomography Angiography (CCTA) 12 months apart, and images will be analyzed.
Up to 30 subjects will receive a single intravenous dose of LUMISIGHT administered 2-12 hours prior to their standard-of-care coronary procedure and experimental intravascular imaging.
Subjects will be imaged with OCT-NIRAF research catheter during their clinically indicated coronary angiogram.
