Abstract：
Invasive functional coronary angiography (FCA), an angiography-derived physiological index of the functional significance of coronary obstruction, is a novel physiological assessment tool for coronary obstruction that does not require the utilization of a pressure wire. This technology enables operators to rapidly evaluate the functional relevance of coronary stenoses during and even after angiography while reducing the burden of cost and complication risks related to the pressure wire. FCA can be used for treatment decision-making for revascularization, strategy planning for percutaneous coronary intervention, and procedure optimization. Currently, various software-computing FCAs are available worldwide, with unique features in their computation algorithms and functions. With the emerging application of this novel technology in various clinical scenarios, the Japanese Association of Cardiovascular Intervention and Therapeutics task force was created to outline expert consensus on the clinical use of FCA. This consensus document advocates optimal clinical applications of FCA according to currently available evidence while summarizing the concept, history, limitations, and future perspectives of FCA along with globally available software.
摘要：
有创功能冠状动脉造影(FCA),冠状动脉阻塞的功能意义的血管造影衍生的生理指标，是一种新颖的冠状动脉阻塞生理评估工具，不需要使用压力线。该技术使操作员能够在血管造影期间甚至之后快速评估冠状动脉狭窄的功能相关性，同时减少与压力线相关的成本负担和并发症风险。FCA可用于血运重建的治疗决策，经皮冠状动脉介入治疗的战略规划，和程序优化。目前,世界各地都有各种软件计算FCA，在他们的计算算法和函数中具有独特的特征。随着这项新技术在各种临床场景中的新兴应用，成立了日本心血管干预和治疗学协会特别工作组,以概述有关FCA临床应用的专家共识.该共识文件根据现有证据，在总结该概念的同时，倡导FCA的最佳临床应用。历史,局限性,以及FCA的未来前景以及全球可用的软件。
