text: When the diagnosis of<unk>  coronary<unk>  dissection (SCAD) cannot be ascertained by the standard coronary angiography, intracoronary<unk>  such as intravascular ultrasound (IVUS) or optical coherence tomography (OCT) may provide complementary information for establishing a definitive diagnosis.  Coronary computed tomography angiography (CCTA) may be useful for non-invasive follow-up of SCAD involving proximal or large-caliber coronary<unk> es. OCT findings suggestive of SCAD may include the presence of two lumens and intramural hematoma.
