导引导管延长是经皮冠状动脉介入治疗(PCI)的组成部分。第一代导引导管延长装置是具有局限性的单轨、钝端管状结构。CrossLiner™是下一代导引延长线“系统”,预期用于安全、深部冠状动脉插管。在头对头研究中,在猪冠状动脉模型中使用GuideLiner™和GuideZilla™对CrossLiner进行了试验,并植入了支架。从4只动物的8条冠状血管中收集数据,以评价使用导引导管延伸段对血管进行深度插管的能力。CrossLiner在8/8条血管中向远端穿过并穿过远端支架节段,而第一代器械卡在支架近端(n=2/8)或支架边缘(n=4/8),或部分进入展开的支架,但困难(2/8)(输送能力p < 0.0002)。CrossLiner和第一代导引导管延长段的导引导管延长段输送/“插管”平均深度分别为12.9±3.6 cm和5.6±1.1 cm(p < 0.001)。CrossLiner是下一代导引延长系统,可能比第一代器械具有优势。需要进一步的临床评价来评估这种新器械在PCI中的作用。
Guide catheter extension is an integral part of percutaneous coronary intervention (PCI). First generation guide catheter extension devices are monorail, blunt ended tubular structures with limitations. The CrossLiner™ is a next generation guide extension “system” intended to allow safe, deep, coronary intubation. The CrossLiner was tested in a head-to-head study with the GuideLiner™ and GuideZilla™ in a porcine coronary model, with stenting. Data were collected from 8 coronary vessels from four animals, to evaluate the ability to deeply intubate the vessel with the guide extension. The CrossLiner crossed distally and through a distal stented segment in 8/8 vessels, while the first-generation devices were stuck proximal to the stent (n=2/8) or at the stent edge (n=4/8), or passed partially into the deployed stent with difficulty (2/8) vessels (p < 0.0002 for deliverability). The average depth of guide extension delivery/ “intubation” was 12.9±3.6 cm for the CrossLiner and 5.6±1.1 cm for the first-generation guide extension (p < 0.001). The CrossLiner is a next generation guide extension system that may offer advantages over first generation devices. Further clinical evaluation will be required to assess the role of this new device in PCI.
