Coronary CT angiography characteristics of OCT-defined thin-cap fibroatheroma: a section-to-section comparison study

Objectives To evaluate whether plaque characteristics as assessed by coronary computed tomography angiography (CCTA) were associated with the presence of a thin-cap fibroatheroma (TCFA)—a precursor of plaque rupture—defined by optical coherence tomography (OCT) in a section-to-section-level comparison.
