Clinical Trial Summary

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.


Description:

1. Hypothesis: The IVUS-guided stent implantation after angiography-derived FFR-based decision-making will show superiority in terms of a lower rate of patients-oriented composite outcomes (POCO) at 24 months after randomization compared with the FFR-guided PCI strategy in patients with coronary stenosis. 2. Research materials and indication for revascularization: 2.1 Experimental group: PCI will be performed if angiography-derived FFR ≤0.80 and will be deferred if angiography-derived FFR >0.80; 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. 2.2 Control group: PCI will be performed if FFR ≤0.80 and will be deferred if FFR >0.80; 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. 3. Sample size: In the post-hoc analysis of the FLAVOUR I study applying QFR analysis, the 2-year POCO rate was 13.0% in the PCI group with FFR ≤0.80 and undergoing FFR-based PCI optimization and 7.1% in the PCI group with QFR ≤0.80 and undergoing IVUS-based PCI optimization. Meanwhile, the 2-year POCO rate was 5.8% and 6.5% in the deferral of PCI group with FFR >0.80 and QFR >0.80, respectively. Assuming a PCI rate of 70% in patients with coronary artery lesions with 50-90% stenosis that is the inclusion criteria for the current study, and considering event rates from historical studies evaluating FFR- and QFR-guided PCI strategies, the cumulative incidence rate of POCO at 24 months was estimated to be 12.0% in the control group (FFR group) and 8.0% in the experimental group (QFR-IVUS group). - Primary endpoint: POCO, defined as a composite of death from any cause, MI, or any revascularization at 24 months after randomization. - Design: superiority - Sampling ratio: experimental group : control group = 1:1 - Type I error (α): Two-sided 5% - Accrual time: 24 months - Total time: 7 years (accrual 24 months + follow-up 60 months) - Assumption: POCO 12.0% vs. 8.0% in control or experimental group, respectively - Statistical power (1- β): 80% - Primary statistical method: Kaplan-Meier survival analysis with log-rank test - Estimated attrition rate: total 10% - Stratification in randomization: Presence of diabetes mellitus Based on the above assumption, we would need total 1,936 patients (968 patients in each group) with consideration of an attrition rate.

Study Design


Intervention

Procedure:
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: PCI will be performed if angiography-derived FFR =0.80 and will be deferred if angiography-derived FFR >0.80. If PCI is performed, PCI optimization using IVUS will be performed following the recommended criteria: ? Plaque burden at stent edge =55%; ? 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: PCI will be performed if FFR =0.80 and will be deferred if FFR >0.80. If PCI is performed, PCI optimization using FFR will be performed following the recommended criteria: ? Post-PCI FFR = 0.88, or ? Post-PCI ?FFR ([FFR at stent distal edge] - [FFR at stent proximal edge]) < 0.05
