“…22 The International Society for Heart and Lung Transplantation-recommended nomenclature classifies CAV into CAV 0 (not significant), CAV 1 (mild), CAV 2 (moderate), and CAV 3 (severe) based on the angiographic appearance of graft coronary arteries. 13 Although patients with CAV 2 and CAV 3 have been shown to be associated with poor prognosis compared with CAV 0 and CAV1, 23 angiography is not suitable to further risk stratify patients with CAV 0 and CAV 1 . Also, in patients with CAV 2 and CAV 3 angiography does not allow plaque characterization and determination of plaque vulnerability.…”
