BACKGROUND: Patients with severe aortic stenosis present frequently (∼50%) with concomitant obstructive coronary artery disease. Current guidelines recommend combined surgical aortic valve replacement (SAVR) and coronary artery bypass grafting (CABG) as the preferred treatment. Transcatheter aortic valve implantation (TAVI) and fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) represent a valid treatment alternative. We aimed to test the non-inferiority of FFR-guided PCI plus TAVI versus SAVR plus CABG in patients with severe aortic stenosis and complex coronary artery disease. METHODS: This international, multicentre, prospective, open-label, non-inferiority, randomised controlled trial was conducted at 18 tertiary medical centres across Europe. Patients (aged ≥70 years) with severe aortic stenosis and complex coronary artery disease, deemed feasible for percutaneous or surgical treatment according to the on-site Heart Team, were randomly assigned (1:1) to FFR-guided PCI plus TAVI or SAVR plus CABG according to a computer-generated sequence with random permuted blocks sizes stratified by site. The primary endpoint was a composite of all-cause mortality, myocardial infarction, disabling stroke, clinically driven target-vessel revascularisation, valve reintervention, and life-threatening or disabling bleeding at 1 year post-treatment. The trial was powered for non-inferiority (with a margin of 15%) and if met, for superiority. The primary and safety analyses were done per an intention-to-treat principle. This trial is registered with ClinicalTrials.gov (NCT03424941) and is closed. FINDINGS: Between May 31, 2018, and June 30, 2023, 172 patients were enrolled, of whom 91 were assigned to the FFR-guided PCI plus TAVI group and 81 to the SAVR plus CABG group. The mean age of patients was 76·5 years (SD 3·9). 118 (69%) of 172 patients were male and 54 (31%) patients were female. FFR-guided PCI plus TAVI resulted in favourable outcomes for the primary endpoint (four [4%] of 91 patients) versus SAVR plus CABG (17 [23%] of 77 patients; risk difference -18·5 [90% CI -27·8 to -9·7]), which was below the 15% prespecified non-inferiority margin (pnon-inferiority<0·001). FFR-guided PCI plus TAVI was superior to SAVR plus CABG (hazard ratio 0·17 [95% CI 0·06-0·51]; psuperiority<0·001), which was driven mainly by all-cause mortality (none [0%] of 91 patients vs seven (10%) of 77 patients; p=0·0025) and life-threatening bleeding (two [2%] vs nine [12%]; p=0·010). INTERPRETATION: The TCW trial is the first trial to compare percutaneous treatment versus surgical treatment in patients with severe aortic stenosis and complex coronary artery disease, showing favourable primary endpoint and mortality outcomes with percutaneous treatment.

BACKGROUND: The clinical impact of a chronic total occlusion (CTO) in patients with 3-vessel coronary artery disease undergoing fractional flow reserve-guided percutaneous coronary intervention (PCI) with current-generation drug-eluting stents or coronary artery bypass grafting (CABG) is unclear. METHODS: The FAME 3 trial (Fractional Flow Reserve Versus Angiography for Multivessel Evaluation 3) compared fractional flow reserve-guided PCI with CABG in patients with 3-vessel coronary artery disease. The primary end point was major adverse cardiac and cerebrovascular events, a composite of death, myocardial infarction, stroke, or repeat revascularization at 1 year. In this substudy, the 3-year outcomes were analyzed in patients with or without a CTO. RESULTS: Of the patients randomized to PCI or CABG in the FAME 3 trial, 305 (21%) had a CTO. In the PCI arm, revascularization of the CTO was attempted in 61% with a procedural success rate of 88%. The incidence of major adverse cardiac and cerebrovascular events at 3 years was not significantly different between those with or without a CTO in both the PCI (15.2% versus 20.1%; adjusted hazard ratio, 0.62 [95% CI, 0.38-1.03]; P=0.07) and the CABG (13.0% versus 12.9%; adjusted hazard ratio, 0.96 [95% CI, 0.55-1.66]; P=0.88) arms. In those without a CTO, PCI was associated with a significantly higher risk of major adverse cardiac and cerebrovascular events compared with CABG (adjusted hazard ratio, 1.61 [95% CI, 1.20-2.17]; P<0.01) but not in those with a CTO (adjusted hazard ratio, 1.21 [95% CI, 0.64-2.28]; P=0.56; Pinteraction=0.31). CONCLUSIONS: The presence of a CTO did not significantly impact the treatment effect of PCI versus CABG at 3 years in patients with 3-vessel coronary artery disease.

BACKGROUND: Previous studies comparing percutaneous coronary intervention (PCI) with coronary artery bypass grafting (CABG) in patients with multivessel coronary disease not involving the left main have shown significantly lower rates of death, myocardial infarction (MI), or stroke after CABG. These studies did not routinely use current-generation drug-eluting stents or fractional flow reserve (FFR) to guide PCI. METHODS: FAME 3 (Fractional Flow Reserve versus Angiography for Multivessel Evaluation) is an investigator-initiated, multicenter, international, randomized trial involving patients with 3-vessel coronary artery disease (not involving the left main coronary artery) in 48 centers worldwide. Patients were randomly assigned to receive FFR-guided PCI using zotarolimus drug-eluting stents or CABG. The prespecified key secondary end point of the trial reported here is the 3-year incidence of the composite of death, MI, or stroke. RESULTS: A total of 1500 patients were randomized to FFR-guided PCI or CABG. Follow-up was achieved in >96% of patients in both groups. There was no difference in the incidence of the composite of death, MI, or stroke after FFR-guided PCI compared with CABG (12.0% versus 9.2%; hazard ratio [HR], 1.3 [95% CI, 0.98-1.83]; P=0.07). The rates of death (4.1% versus 3.9%; HR, 1.0 [95% CI, 0.6-1.7]; P=0.88) and stroke (1.6% versus 2.0%; HR, 0.8 [95% CI, 0.4-1.7]; P=0.56) were not different. MI occurred more frequently after PCI (7.0% versus 4.2%; HR, 1.7 [95% CI, 1.1-2.7]; P=0.02). CONCLUSIONS: At 3-year follow-up, there was no difference in the incidence of the composite of death, MI, or stroke after FFR-guided PCI with current-generation drug-eluting stents compared with CABG. There was a higher incidence of MI after PCI compared with CABG, with no difference in death or stroke. These results provide contemporary data to allow improved shared decision-making between physicians and patients with 3-vessel coronary artery disease. REGISTRATION: URL: https://www.

BACKGROUND: Patients with three-vessel coronary artery disease have been found to have better outcomes with coronary-artery bypass grafting (CABG) than with percutaneous coronary intervention (PCI), but studies in which PCI is guided by measurement of fractional flow reserve (FFR) have been lacking. METHODS: In this multicenter, international, noninferiority trial, patients with three-vessel coronary artery disease were randomly assigned to undergo CABG or FFR-guided PCI with current-generation zotarolimus-eluting stents. The primary end point was the occurrence within 1 year of a major adverse cardiac or cerebrovascular event, defined as death from any cause, myocardial infarction, stroke, or repeat revascularization. Noninferiority of FFR-guided PCI to CABG was prespecified as an upper boundary of less than 1.65 for the 95% confidence interval of the hazard ratio. Secondary end points included a composite of death, myocardial infarction, or stroke; safety was also assessed. RESULTS: A total of 1500 patients underwent randomization at 48 centers. Patients assigned to undergo PCI received a mean (±SD) of 3.7±1.9 stents, and those assigned to undergo CABG received 3.4±1.0 distal anastomoses. The 1-year incidence of the composite primary end point was 10.6% among patients randomly assigned to undergo FFR-guided PCI and 6.9% among those assigned to undergo CABG (hazard ratio, 1.5; 95% confidence interval [CI], 1.1 to 2.2), findings that were not consistent with noninferiority of FFR-guided PCI (P = 0.35 for noninferiority). The incidence of death, myocardial infarction, or stroke was 7.3% in the FFR-guided PCI group and 5.2% in the CABG group (hazard ratio, 1.4; 95% CI, 0.9 to 2.1). The incidences of major bleeding, arrhythmia, and acute kidney injury were higher in the CABG group than in the FFR-guided PCI group. CONCLUSIONS: In patients with three-vessel coronary artery disease, FFR-guided PCI was not found to be noninferior to CABG with respect to the incidence of a composite of death, myocardial infarction, stroke, or repeat revascularization at 1 year.
