摘要
L/P比值表示血管管腔容积与斑块容积的比例，病变的L/P比值低于每个病变的L/P比值（RCA，0.9 vs. 7.7；LAD，1.4 vs. 8.1；LCX，0.9 vs. 8.0）。对于位于三条主要血管中段的病变，FFRCT 分别从 0.97 降至 0.78（RCA）、0.94 降至 0.55（LAD）和 0.99 降至 0.72（LCX）。有创冠状动脉造影显示 RCA 中段中度狭窄，但在 FFRCT 显示 LAD 和 LCX 大幅下降的部位没有明显的阻塞性冠状动脉疾病。CCTA表示冠状动脉CT血管造影；ICA表示侵入性冠状动脉血管造影；LAD表示左前降支动脉；LCX表示左侧环状动脉；RCA表示右冠状动脉；SOCAD表示明显阻塞性冠状动脉疾病。
Impact of Heterogeneous Plaque Deposition on Computed Tomography Derived Fractional Flow Reserve
L/P ratio, which indicates the proportion of lumen volume to plaque volume of the vessel, is lower in lesion than in per-lesion (RCA, 0.9 vs. 7.7; LAD, 1.4 vs. 8.1; and LCX, 0.9 vs. 8.0). For lesion located in the middle segments of the three major vessels, FFRCT drops from 0.97 to 0.78 for RCA, from 0.94 to 0.55 for LAD, and from 0.99 to 0.72 for LCX, respectively. Invasive coronary angiography shows moderate stenosis in the middle segment of the RCA but no significant obstructive coronary disease at the sites where FFRCT showed a substantial decline in the LAD and LCX. CCTA indicates coronary CT angiography; ICA, invasive coronary angiography; LAD, left anterior descending artery; LCX, left circumflex artery; RCA, right coronary artery; SOCAD, significant obstructive coronary disease.
