BBC ONE The British Bifurcation Coronary study: Old, New and Evolving strategies A randomized comparison of simple versus complex drug-eluting stenting for bifurcation lesions

BBC ONE Inclusion criteria >18 yrs Stable or unstable angina Bifurcation types I-IV suitable for stenting of both vessels Vessel diameters >2.25mm side, >2.5mm main

(according to operator preference) BBC ONE Simple – provisional T-stenting Following main vessel stenting, the side branch should not be treated further unless there is: <TIMI 3 flow in the side branch Severe ostial pinching (>90%) of the side branch Threatened side vessel closure Side-branch dissection >type A Complex – crush or culotte (according to operator preference)

Primary endpoints (9 months) BBC ONE Primary endpoints (9 months) Death Target vessel failure main vessel or side branch TIMI<3 (after vasodilators) on further angiogram main vessel or side branch undergoes attempted repeat PCI/CABG Myocardial infarction
