One of the potential complications of transcatheter aortic valve implantation (TAVI) is coronary obstruction (CO), which can occur by displacement of heavily calcified native valve cusps against the coronary ostium. Treatment mandates immediate percutaneous coronary intervention (PCI) to restore coronary flow and improve hemodynamics and if unsuccessful, urgent implementation of circulatory support, commonly extracorporeal, with subsequent surgical revascularization. We report a case of post-TAVI CO for which successful emergent deployment of Impella percutaneous mechanical circulatory support to restore hemodynamic stability facilitated definitive treatment with bilateral PCI. Impella support represents an expeditious, effective, and widely available therapy to complement and facilitate PCI in the treatment of CO complicating TAVI, and may diminish requirement for urgent coronary artery bypass surgery. © 2015 Wiley Periodicals, Inc.
经导管主动脉瓣植入术(TAVI)的潜在并发症之一是冠状动脉阻塞(CO),其可因严重钙化的自身瓣膜叶移位至冠状动脉口而发生。治疗要求立即进行经皮冠状动脉介入治疗(PCI)以恢复冠状动脉血流并改善血流动力学,若治疗失败,则紧急实施循环支持,通常是体外循环支持,随后进行外科血管重建。我们报告了一例TAVI术后CO的病例,其中成功紧急部署Impella经皮机械循环支持以恢复血流动力学稳定性,从而促进了双侧PCI的确定性治疗。Impella支持是一种快速、有效且广泛可用的治疗方法,可在治疗TAVI并发的CO时补充并促进PCI,且可能减少紧急冠状动脉搭桥手术的需求。© 2015威利期刊公司。
