"QFR is expected to be in parallel with FFR. In addition, for the three advantages of wire free, non-invasive, and fast assessment, QFR is expected to replace FFR in some clinical applications in the future. Whether QFR will become an indispensable clinical tool for cardiologists depends on further QFR clinical research."

"QFR requires no wire or adenosine, and can fast assess the functional significance of coronary stenosis in the Cath Lab. I believe QFR has the prospect to be a powerful tool for optimizing PCI."

Cardiologist, Peking University Third Hospital

"About 50% (about 330,000 cases per year) of the patients underwent PCI in China should have undergone coronary arterial functional evaluation. QFR examination has great clinical value for the patients whose lesions are difficult to determine."

Director of Cardiology Dept., Shanghai Chest Hospital

"QFR, as a novel detection method for testing coronary arterial function, has the characteristics of non-invasiveness, simplicity, rapidity, and precision. It has greatly expanded the detection population and will encourage more patients to undergo functional testing, which will help guide the design of clinical strategies. The current data shows that the QFR is extremely in line with FFR, so clinical trials using QFR to guide PCI practice should be designed as soon as possible to verify its clinical application value. "

Cardiologist, Guangdong General Hospital

"QFR is not only an alternative to FFR, but also an extension of FFR indications. It avoids the interference of the guide wire and may reflect the true state of blood vessels and lesions better compared with FFR."
