Predictors of 1- and 12-month mortality in bifurcation coronary intervention: a contemporary perspective Supplementary Data

Aim: Bifurcation-PCI is performed frequently, although without extensive evidence to back up a definitive

solution for its complexity. We set out to identify factors associated with 1- and 12-month mortality after

bifurcation-PCI between 2017 and 2021 in our tertiary centre in Wales, UK. Results: Of 732 bifurcation

PCI cases (mean age 69; 25% female), 67% were in ACS, 42% were left main PCI and 25.3% involved

two-stent strategy. 30-day and 12-month mortality were 1.9% and 8.2%, respectively. Age, diabetes,

smoking and renal failure are associated with mortality after bifurcation-PCI, while the choice between

provisional and 2-stent strategies did not impact mortality/TLR. Conclusion: Awareness of ‘real-world’

outcomes of bifurcation-PCI should be used for appropriate patient selection, technique planning and

procedural consent.
