The European Bifurcation Club Randomized Trial of Stepwise Provisional Stenting Versus Drug Coated Balloon Therapy for Non-left Main True Coronary Bifurcations

Официальное название

The European Bifurcation Club Randomized Trial of Stepwise Provisional Stenting Versus Drug Coated Balloon Therapy for Non-left Main True Coronary Bifurcations - EBC DCB Study

Обзор

Clinical outcomes are worse in patients with coronary artery bifurcation lesions, even if commonly encountered in clinical practice. The use of drug coated balloons within bifurcation lesions offers the acute advantage of a more straightforward procedure, without recrossing and deformation of a stent. Thus, the primary objective of this study is to determine if Drug Coated Balloon treatment of non-left main true coronary artery bifurcation lesions is non-inferior (similar) to a provisional strategy with Drug Eluted Stent deployment.

Подробное описание

The EBC DCB study is an investigator-initiated, prospective, multi-centre, open-label, randomized (1:1) non-inferiority trial.

Patients with non-left main bifurcations requiring revascularisation and both the main vessel and side branch significantly diseased ( ≥2.5mm and Medina 1/1/1, 1/0/1 or 0/1/1), constitute the source population. Patients with no more than two additional coronary disease may be considered for the study, with only one bifurcation lesion included.

Patients, pre-selected by their referring physicians, will be screened for eligibility by the study team. If patients fulfill all inclusion and do not meet exclusion criteria, they will be informed about the study's purpose and course and will be asked for participation and written informed consent. 20 sites will be involved, in 7 European countries and South Korea, for a total of 750 patients. After a 2-years recruitment period, the trial will include a Follow-Up period at 6-months, 1-year, 3-years, 5-years and 8-years. The 1-year check point will constitute the primary endpoint where the Bifurcation Orientated Composite Endpoint (BOCE) will be analyzed for non-inferiority (further analysis for superiority, if non-inferiority met).

Вмешательства

• Процедура Percutaneous Coronary Angioplasty
  A Percutaneous Coronary Intervention is used in both arms, with the drug Zotarolimus for stenting strategy and Paclitaxel for balloon strategy. Coronary guide wires are passed into both the distal main vessel (distal MV) and side branch (SB) and predilation of MV on a 1:1 basis is required. The device component dilates the vessel lumen by Percutaneous Transluminal Coronary Angioplasty (PTCA), while the drug is intended to reduce the proliferative response associated with restenosis.
• Устройство Stepwise Provisional Stent Strategy
  In the stepwise provisional stent strategy, stenting of the MV is undertaken with a wire jailed in the SB. Then, non-compliant balloons sized to the diameter of the distal MV and SB are sequentially inflated at high pressure, and then simultaneously at low pressure (kissing balloon inflation ; KBI).
• Устройство Drug Coated Balloon Strategy
  In the drug coated balloon (DCB) strategy, SB is prepared with a balloon at a 1:1 diameter, followed with a 1:1 sized DCB inflation for 60 seconds at nominal pressure. Then, MV is re-evaluated and treated with DCB at nominal pressure only, sized 1:1 with the proximal MV, for 60 seconds.
• Устройство Cross-Over Stepwise Provisional Stent Strategy
  Following Drug Coated Balloon treatment in the Main vessel (MV) in the Drug Coated Balloon Arm, if the result is unacceptable in the MV, with either TIMI\>3 flow and/or dissection propagation, MV stenting is mandatory followed with Kissing Balloon Inflation (KBI), where non-compliant balloons sized to the diameter of the distal main and side branch are sequentially inflated at high pressure, and then simultaneously at low pressure. If the cross-over stent implantation in the MV is used, a furthe
