2023年4月10日 · Objectives: The AQVA (Angio-based Quantitative Flow Ratio Virtual PCI Versus Conventional Angio-guided PCI in the Achievement of an Optimal Post-PCI QFR) trial aims to test whether a QFR-based virtual percutaneous coronary intervention (PCI) is superior to a conventional angiography-based PCI at obtaining optimal post-PCI QFR results.

2023年5月12日 · 结果：Post-PCI QFR最佳 阈值是0.89 ；Post-PCI QFR阈值评价患者远期VOCE事件，两者发生风险 高达7倍 ；AUC 0.77，敏感性60%，特异性87%。 结论：Post-PCI QFR是术后不良事件的独立预测因子，QFR值越低，风险越高。

The AQVA (Angio-based Quantitative Flow Ratio Virtual PCI Versus Conventional Angio-guided PCI in the Achievement of an Optimal Post-PCI QFR) trial aims to test whether a QFR-based virtual percutaneous coronary intervention (PCI) is superior to a conventional angiography-based PCI at obtaining optimal post-PCI QFR results.

2024年4月10日 · Cardiologists used QFR readings for decision-making, with QFR >0.80 indicating non-significance and <0.80 denoting significant stenosis, prompting angioplasty. The lesions were re-evaluated post-angioplasty and QFR >0.90 indicated that no further intervention was necessary. Results: A total of 770 subjects were screened.

2021年11月8日 · qfr作为无创的计算冠脉生理学评估技术，可在术中实时分析得到ffr值，同时还具有pci手术规划和虚拟支架功能。 大量临床研究已证实QFR的可行性及有效性。

2023年10月9日 · In this regard, the current study reanalyzed the FRAME-AMI trial population using the quantitative flow ratio (QFR) to evaluate what proportion of non-IRA lesions in the angiography-guided PCI group was functionally insignificant and what the prognostic impact of angiography-guided PCI for functionally insignificant non-IRA lesions in patients w...

2023年8月7日 · Objective: To investigate the predictive value of quantitative flow ratio (QFR) for adverse events (vessel-oriented composite endpoint events/target lesion failure) in patients after percutaneous coronary intervention (PCI). Method: Eight studies involving 4,173 patients (5,688 vascular lesions) were included. These are studies on the ...

2023年5月18日 · 欧洲经皮心血管介入治疗协会（EAPCI）发布 2023年最新应用冠脉功能学进行PCI规划与指导的专家共识，详细阐述了应用QFR指导PCI介入治疗的全流程，并强调： 博动QFR是唯一被证明能改善临床预后的基于造影的血流储备分数（FFR）工具。 本次发布的EAPCI临床共识主要目的是就应用冠状动脉生理学评估技术进行PCI手术规划、病变类型识别和PCI预后优化提供最新证据和专家意见 [1]。 从确定手术适应症到规划和指导PCI. 当既往没有心肌缺血的证 …

2021年11月8日 · 定量血流分数 qfr 是由博动自主研发、拥有自主知识产权的计算冠脉生理学评估技术，无需使用压力导丝或血管扩张药物，即可准确评估心肌缺血严重程度，指导介入干预治疗策略。

2024年9月25日 · Murray law-based QFR (μQFR) is a new method for physiological assessment that has higher feasibility and efficiency. The purpose of this study was to investigate the performance of μQFR-guided virtual PCI in improving post-PCI outcomes.
