Off-label "double-wire" technique for closure of large-bore vascular access has been reported in the setting of percutaneous aortic valvuloplasty. We present 5 cases of high-risk percutaneous coronary intervention (HRPCI) supported by a 2.5 LP Impella assist device with 13 and 14 Fr size femoral access. Following successful HRPCI, vessel closure was complicated by unsuccessful deployment of a suture-mediated closure device. Subsequently, deployment of two successive collagen-based closure devices with a "double-wire" technique was performed. Our cases warrant further studies to test the feasibility of using double-closure device as an alternative for vessel closure when left ventricular assist devices are needed to support HRPCI.
在经皮主动脉瓣成形术的背景下，已有关于非标签“双线”技术用于闭合大口径血管通路的报道。我们介绍了5例高危经皮冠状动脉介入治疗（HRPCI），这些病例由2.5 LP Impella辅助装置支持，采用13和14 Fr尺寸的股动脉通路。在成功完成HRPCI后，血管闭合因缝线介导的闭合装置部署失败而变得复杂。随后，采用“双线”技术连续部署了两个基于胶原蛋白的闭合装置。我们的病例值得进一步研究，以测试在需要左心室辅助装置支持HRPCI时，使用双重闭合装置作为血管闭合替代方法的可行性。
