µQFR for Branch Stenosis After Single Stent in Bifurcation Lesions

Patients with bifurcation lesions undergoing single-stent intervention are recruited. Wire-based FFR and intravascular imaging is performed, according to current guidelines, to guide PCI strategy. Angiography will be saved anonymously and sent to an independent core lab for µQFR calculation. Operaters are blinded to µQFR results.
