Coronary bifurcation lesions present a challenging lesion subset regarding procedural complexity and worse patient outcomes as compared to simple lesions. Drug eluting stents (DES), as the current standard of care for percutaneous myocardial revascularization, have tubular design and uniform diameter, and therefore, need to be subjected to a standardized set of procedural modifications, to optimally fit and reconstruct underlying bifurcation anatomy. Since contemporary DES have various design platforms, with diverse mechanical properties, we must be aware of the device's favorable characteristics and limitations, to ensure maximal procedural safety and success. This is especially true for bifurcation lesion stenting, during which device integrity will often be eventually tested by undergoing specific procedural steps, such as proximal balloon optimization, kissing-balloon inflations, or even intentional stent crushing. In this review we address the design characteristics of contemporary DES, their bifurcation-specific experimental testing data, and reported clinical results, in an attempt to provide relevant information and help in device selection for bifurcation stenting procedures.
与简单病变相比,冠状动脉分叉病变在手术复杂性和较差的患者预后方面是一个具有挑战性的病变亚组。药物洗脱支架(DES)作为经皮心肌血运重建的当前标准治疗方法,具有管状设计和统一直径,因此,需要进行一系列标准化的手术改良,以最佳地适应和重建潜在的分叉解剖结构。由于当代DES具有各种设计平台,机械性能各不相同,我们必须了解该装置的有利特性和局限性,以确保最大的手术安全性和成功率。对于分叉病变支架置入术尤其如此,在此过程中,装置完整性通常最终会通过特定的手术步骤进行测试,例如近端球囊优化、双球囊扩张,甚至故意挤压支架。在本综述中,我们阐述了当代DES的设计特点、其针对分叉病变的实验测试数据以及报道的临床结果,试图提供相关信息并有助于分叉支架置入术的器械选择。
