Coronary bifurcations exhibit localised turbulent flow and an enhanced propensity for atherothrombosis, platelet deposition and plaque rupture. Percutaneous coronary intervention (PCI) of bifurcation lesions is associated with an increased risk of thrombotic events. Such risk is modulated by anatomical complexity, intraprocedural factors and pharmacological therapy. There is no consensus on the appropriate PCI strategy or the optimal regimen and duration of antithrombotic treatment in order to decrease the risk of ischaemic and bleeding complications in the setting of coronary bifurcation. A uniform therapeutic approach meets a clinical need. The present initiative, promoted by the European Bifurcation Club (EBC), involves opinion leaders from Europe, America, and Asia with the aim of analysing the currently available evidence. Although mainly derived from small dedicated studies, substudies of large trials or from authors' opinions, an algorithm for the optimal management of patients undergoing bifurcation PCI, developed on the basis of clinical presentation, bleeding risk, and intraprocedural strategy, is proposed here.
冠状动脉分叉处存在局部湍流,更容易发生动脉粥样硬化血栓形成、血小板沉积和斑块破裂。经皮冠状动脉介入治疗(PCI)分叉病变与血栓事件风险增加相关。这种风险受解剖复杂性、术中因素和药物治疗的调节。目前对于如何降低冠状动脉分叉处缺血和出血并发症的风险,尚无关于适当 PCI 策略或最佳抗栓治疗方案和持续时间的共识。统一的治疗方法符合临床需求。本倡议由欧洲分叉俱乐部(EBC)发起,涉及来自欧洲、美洲和亚洲的意见领袖,旨在分析现有证据。虽然主要来自于小型专门研究、大型试验的亚组研究或作者的意见,但此处提出了一种基于临床表现、出血风险和术中策略的分叉 PCI 患者最佳管理算法。
