The REVEALPLAQUE Study: A pRospEctiVe, multicEnter Study to AnaLyze PLAQUE Using CCTA (REVEALPLAQUE)

This study will evaluate the level of agreement between noninvasive CCTA-based quantification and characterization of coronary atherosclerosis and invasive IVUS .
Condition or disease
Coronary Artery Disease
This is a prospective, multi-center study. All patients who have a stenosis in at least one major epicardial vessel confirmed by CCTA, who have undergone FFRCT analysis, and who are scheduled to undergo clinically indicated IVUS-guided invasive evaluation and/or treatment will be eligible for enrollment. Enrolling sites will have FFRCT analysis incorporated when indicated into their standard evaluation of CCTA scans. Data collected will include CCTA and FFRCT, full angiographic, and IVUS images, and if obtained, any other imaging or physiologic data including OCT, FFR, any NHPR (e.g., dPR, RFR, iFR, etc.), and pre- and post-stent implantation invasive data. All non-invasive and invasive data collected will be obtained as clinical practice consistent with standard clinical care.

Ages Eligible for Study:
18 Years and older (Adult, Older Adult)
Sexes Eligible for Study:
Accepts Healthy Volunteers:
Clinically stable patients with known CAD who have a CCTA showing stenosis in at least one major epicardial vessel of stentable/graftable diameter and in whom clinically-indicated IVUS is planned.
Inclusion criteria (all must be present):
