Abstract

Coaxial trapping of guide extension catheters within a coronary artery allows for maximal support in delivering equipment; however, use of this technique within the left main coronary artery has been avoided due to concerns surrounding hemodynamic instability and vessel injury. We describe our initial experience with impromptu coaxial trapping of guide extension catheters within the left main coronary artery using the dual access rapid trap (DART) technique. Coaxial trapping of guide extension catheters within the left main coronary artery using DART enabled successful equipment delivery across balloon-uncrossable lesions. This case demonstrates that DART is a safe and effective method for equipment delivery across balloon-uncrossable lesions and may aid operators in safely solving complex cases.

用于增强左冠状动脉系统导引导管支持的双通道快速捕获器

在冠状动脉内同轴诱捕导引延长导管可以最大限度地支持设备的输送；但是，由于担心血流动力学不稳定和血管损伤，在左冠状动脉主干内一直避免使用这种技术。我们介绍了在左冠状动脉主干内使用双通道快速捕获（DART）技术临时同轴捕获导引延长导管的初步经验。使用 DART 在左冠状动脉主干内同轴诱捕导引延长导管，成功地在球囊无法穿越的病变部位进行了设备输送。本病例表明，DART 是一种安全有效的方法，可在球囊无法穿越的病变处输送设备，有助于操作人员安全地解决复杂病例。
