Treatment of Bifurcation Lesions by Bail-Out TAP or Culotte: Lost in Translation?

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 with CBL.\r\n\r\nMETHODS:\r\nThe 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
