FFR Versus IVUS with Angiography-Derived FFR for Clinical Outcomes in Patients with Coronary Artery Disease
Comparison of Fractional Flow Reserve-Guided Strategy Versus Intravascular Ultrasound-Guided Stent Implantation After Angiography-Derived Fractional Flow Reserve-based Decision-Making (The FLAVOUR III Trial)
About This Trial
To compare the clinical outcomes of fractional flow reserve (FFR)-guided strategy versus intravascular ultrasound (IVUS)-guided stent implantation after angiography-derived FFR-based decision-making.

Treatments Being Tested
Intravascular ultrasound-guided stent implantation after angiography-derived FFR-based decision-making
The percutaneous coronary intervention will be performed by intravascular ultrasound (IVUS)-guided strategy after angiography-derived FFR-based decision-making: 1. PCI will be performed if angiography-derived FFR ≤0.80 and will be deferred if angiography-derived FFR \>0.80. 2. If PCI is performed, PCI optimization using IVUS will be performed following the recommended criteria: ① Plaque burden at stent edge ≤55%; ② Minimal stent area ≥ 5.5 mm2, or minimal stent area ≥ distal reference lumen area
Fractional flow reserve-guided PCI strategy
The percutaneous coronary intervention will be performed by fractional flow reserve (FFR)-guided strategy: 1. PCI will be performed if FFR ≤0.80 and will be deferred if FFR \>0.80. 2. If PCI is performed, PCI optimization using FFR will be performed following the recommended criteria: ① Post-PCI FFR ≥ 0.88, or ② Post-PCI ΔFFR (\[FFR at stent distal edge\] - \[FFR at stent proximal edge\]) \< 0.05
