研究目的: |
血流储备分数(Fractional Flow Reserve, FFR)测定已成为评价冠状动脉血管生理学功能的有效方法。FFR=Pd/Pa(Pa为冠状动脉口处的主动脉压,Pd为冠脉狭窄远端压力),当FFR≤0.80时,所代表的狭窄情况可能会导致心肌缺血;当FFR>0.80时,所代表的狭窄会造成心肌缺血的可能性非常小。目前大多数的FFR测量都是基于压力导丝介导,但因为高昂的费用及手术风险在我国的普及度较低。 CAFFR是一种创新的评估冠脉狭窄功能学意义的方法。CAFFR可以通过血管三维重建和血流动力学模拟计算得到,无需血管扩张药物和压力导丝。前期科学研究的结果表明CAFFR具有极大的临床应用价值,所以本次研究的主要目的是在实时手术过程中以 FFR(压力导丝测量的血流储备分数)为对照,评价冠状动脉分析系统以及一次性使用血压传感器测量的冠脉造影血流储备分数(coronary angiography Fractional Flow Reserve,CAFFR)在线评估心脏冠脉功能学意义的可行性、准确度和安全性。 |

|
Objectives of Study: |
The measurement of Fractional Flow Reserve (FFR) has become an effective method to evaluate the physiological function of coronary arteries, FFR=Pd/Pa (Pa is the aortic pressure, and Pd is the pressure distal to coronary artery stenoses). When FFR ≤0.80, the stenosis leads to myocardial ischemia. When FFR > 0.80, the stenosis is unlikely to cause myocardial ischemia. FFR is generally measured by a pressure wire. CAFFR (Coronary Angiography Fractional Flow Reserve) is an innovative system to assess the functional significance of coronary stenoses without invasive pressure wire and hyperemic stimulus, based on the specially-designed computational fluid dynamics (CFD) and coronary angiography. The aim of the study is to carry out a prospective and multicenter trial to assess the on-site diagnostic performance (e.g., feasibility, accuracy, and safety) of CAFFR in the catheterization laboratory. |

|
药物成份或治疗方案详述: |
这是一个关于医疗器械的非随机、自身对照试验。受试者先接受CAFFR检测再接受FFR检测。FFR由压力导丝测量得到,CAFFR由冠状动脉分析系统和一次性使用血压传感器测量得到。同一个受试者的两个测量结果将被放在一起比较。 |

|
Description for medicine or protocol of treatment in detail: |
This is a non-randomized and self-controlled clinical study to assess the medical device of CAFFR. Subjects demonstrate the CAFFR measurement, followed by the FFR measurement using a classical pressure wire. Aortic pressure is measured by a blood pressure transducer connected to the catheter. Coronary angiograms and aortic pressure are input to CAFFR to determine FFR in coronary arteries with lesions. The on-site diagnostic accuracy of CAFFR was evaluated in blinded fashion against the wire-based FFR using a cutoff value of 0.80 and re-evaluated off-site at an independent core laboratory. The primary endpoint was that ±95% confidence interval (CI) of the assessment exceeded 84%. |
