In OCT, plaque protrusion is characterized by a smooth surface and no signal attenuation, and thrombus protrusion by irregular surface and significant signal attenuation. OCT can provide better images and clearer visualization of tissue protrusion compared with IVUS. Tissue protrusion is more frequently in the culprit lesions of acute coronary syndromes, as unstable lesions contain soft lipid tissue and thrombi. In a multicenter registry, including 780 patients, 50% ACS, irregular protrusion was more common in patients treated for MI and was an independent predictor of target lesion revascularization. In fact, tissue prolapse has a worse clinical impact in ACS as suggested in CLI‐OPCI substudies [54].
