Background: Coronary bifurcated lesions (CBL) represent a hot topic of interventional
cardiology. Provisional stenting, i.e. implantation of a drug-eluting (DES) in the main branch followed
by side-branch (SB) intervention in case of suboptimal SB result, represents the gold standard to treat
the vast majority of CBL undergoing percutaneous coronary interventions (PCI). The best technique
for bail-out SB stenting has not been established. Prospective randomized trials comparing different
stenting techniques may help provide important insights regarding the best way to conduct PCI in patients
Methods: The recently published Bifurcations Bad Krozingen (BBK) II trial is the last important randomized
study in the field of bifurcation PCI and is focused on the search for the best management of
those patients with suboptimal SB result during provisional stenting. Two different SB implantation
strategies after provisional stenting have been compared. In the present manuscript, we employed
BBK II results in the context of available literature highlighting important specific features of the
study with main emphasis on patient selection process and techniques applied.
