简要总结
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.
详细描述
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).
