摘要
目前血流储备分数(FFR)被认为是心外膜冠状动脉狭窄功能性评价的“金标准”,但由于各种原因在实际临床中FFR的应用受到一定限制。基于冠状动脉CT血管造影(CCTA)影像数据应用高级计算流体力学及深度学习等方法获得的冠状动脉CT血流储备分数(CT-FFR)能同时提供冠状动脉的解剖和生理学信息,成为临床研究和应用的新热点。CT-FFR在国内临床实践中的使用仍处于探索阶段。本专家共识介绍了CT-FFR的基本原理及诊断效能、工作流程、临床证据、应用临床路径及局限性。专家组希望本临床路径共识的制订与发布能够对未来CT-FFR技术的临床规范化使用起到积极推动作用。
Fractional flow reserve(FFR)is considered the“gold standard”for functional evaluation of epicardial coronary artery stenosis,but its application in clinical practice is limited due to various reasons.Coronary CT angiography derived fractional fl ow reserve(CT-FFR)obtained based on coronary CT angiography(CCTA)images and advanced computational fl uid dynamics and deep learning methods can simultaneously provide anatomical and physiological information of coronary arteries.CT-FFR has became a new hotspot in clinical research and application.The use of CT-FFR in domestic clinical practice is still in the exploratory stage.This expert consensus introduces the basic principles and diagnostic performance of CT-FFR,the workfl ow of CT-FFR,the clinical evidence of CT-FFR,the clinical pathway of CT-FFR application,and the limitations of CT-FFR.The aim of this expert consensus is to promote the standardized application of CT-FFR in clinical practice.
