Evidence-based use of intravascular imaging. The ability of OCT and IVUS to evaluate specific factors in PCI is depicted as following: 5 rhombi = highly recommended, 4 rhombi = recommended, 3 rhombi = feasible, 2 rhombi = under investigation, 1 rhombus = not feasible. ^{1,3,4,5,6,7,12} High recommendation based on the latest guidelines [27, 28]. ² For early-stage post-PCI [7, 8]. ⁸ [5, 38, 71]. ⁹ [21, 69]. ¹⁰ [7, 10]. ¹¹ [74, 78, 88]. ¹³ [28, 43, 44]. ¹⁴ [47, 48, 49]. ¹⁵ [53, 55, 57]. ¹⁶ [60, 61, 62, 63].
