12. 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)
