Lower values of QFR after complete and successful revascularization is associated with 3-time increase in the risk of subsequent adverse events

In the FAVOR III China trial, we investigated whether utilizing quantitative flow ratio (QFR) guidance in lesion selection for percutaneous coronary intervention (PCI) could improve clinical outcomes compared to standard angiography guidance.

We introduced this new section to share tips across all product lines. By sharing this, we want to transfer the knowledge we receive from you and all your peers and enable the use of Medis software to its full potential.

QFR-based virtual PCI is superior to conventional angiography-based PCI at achieving optimal post-PCI physiology results without significantly increasing procedural time, contrast due or X-ray use.
