Percutaneous coronary intervention (PCI) has been increasingly performed in patients with severely depressed left ventricular function and complex coronary lesions, including multivessel disease. Mechanical ventricular assist devices play an increasingly important role in high-risk PCI. Impella CP (Abiomed, Inc.) is a new percutaneous left ventricular assist device, designed for short-term circulatory support. It is a promising option for hemodynamic support in high-risk procedures and can potentially reduce PCI-related complications. The authors present two case reports of high-risk PCI using the Impella CP device. In the setting of low coronary flow reserve, severely depressed left ventricular function and potential hemodynamic instability, the Impella CP device has made it possible to maintain hemodynamic stability during procedures, without being associated with vascular complications.
经皮冠状动脉介入治疗（PCI）越来越多地应用于左心室功能严重受损且伴有复杂冠状动脉病变（包括多支血管病变）的患者。机械心室辅助装置在高危PCI中发挥着越来越重要的作用。Impella CP（Abiomed公司）是一种新型经皮左心室辅助装置，设计用于短期循环支持。它是高危手术中血流动力学支持的一个有前景的选择，并有可能减少与PCI相关的并发症。作者介绍了两例使用Impella CP装置进行高危PCI的病例报告。在冠状动脉血流储备低、左心室功能严重受损和潜在血流动力学不稳定的情况下，Impella CP装置使得在手术过程中维持血流动力学稳定成为可能，且未出现血管并发症。
