Impact of Bifurcation Lesions on Outcomes After FFR-Guided PCI or CABG

Abstract

Background: In the era of first-generation drug-eluting stents and angiography-guided percutaneous coronary intervention (PCI), the presence of a bifurcation lesion was associated with adverse outcomes after PCI. In contrast, the presence of a bifurcation lesion had no impact on outcomes following coronary artery bypass grafting (CABG). Therefore, the presence of a coronary bifurcation lesion requires special attention when choosing between CABG and PCI. The aim of this study is to assess whether the presence of a bifurcation lesion still influences clinical outcomes after contemporary PCI using second-generation drug-eluting stent and fractional flow reserve (FFR) guidance versus CABG.

Methods: The randomized FAME 3 trial (Fractional Flow Reserve Versus Angiography for Multivessel Evaluation) compared FFR-guided PCI using current drug-eluting stents with CABG in patients with 3-vessel coronary artery disease. The prespecified key end point at 3-year follow-up was the composite of death, myocardial infarction, or stroke. In this substudy, the impact of bifurcation lesions on outcomes after FFR-guided PCI and CABG was investigated.

Results: The FAME 3 trial enrolled 1500 patients and 653 (45.2%) patients had at least 1 true bifurcation lesion. There was no difference in the composite of death, myocardial infarction, or stroke at the 3-year follow-up between patients with or without at least 1 true bifurcation lesion (11.6% versus 10.0%; hazard ratio, 1.17 [95% CI, 0.86-1.61]; =0.32), regardless of revascularization strategy. The composite end point was not statistically different between FFR-guided PCI and CABG in patients with at least 1 true bifurcation lesion (hazard ratio, 1.27 [95% CI, 0.80-2.00]) or without a true bifurcation lesion (hazard ratio, 1.36 [95% CI, 0.87-2.12]), with no significant interaction (=0.81).

Conclusions: In patients with 3-vessel coronary artery disease, the presence of a true bifurcation lesion was not associated with a different treatment effect after FFR-guided PCI with contemporary drug-eluting stent versus CABG.
