Percutaneous coronary intervention (PCI) has been increasingly applied to patients with severely depressed left ventricular function and complex coronary lesions. The availability of hemodynamic support devices offers a promising option to reduce PCI-related complications in high-risk procedures. We report the case of a 79-year-old man who suffered from unstable angina. The coronary angiogram revealed multivessel disease including a significant distal left main (LM) stenosis. Additionally, the patient had a history of chronic lymphatic leukemia with immune hemolysis. Therefore, the patient was considered to be at exceptionally high mortality risk in case of cardiac surgery. We decided to perform a percutaneous revascularization of the LM supported by the Impella Recover LP 2.5 assist device. This case report discusses the principles of indications, technique and complications of this new addition to interventional cardiology.
经皮冠状动脉介入治疗（PCI）已越来越多地应用于左心室功能严重受损和复杂冠状动脉病变的患者。血流动力学支持设备的出现为降低高风险手术中与PCI相关的并发症提供了一个有前景的选择。我们报告一例79岁男性不稳定型心绞痛患者的病例。冠状动脉造影显示多支血管病变，包括显著的左主干（LM）远端狭窄。此外，该患者有慢性淋巴细胞白血病伴免疫性溶血病史。因此，该患者被认为在进行心脏手术时死亡风险极高。我们决定在Impella Recover LP 2.5辅助设备支持下对左主干进行经皮血管重建术。本病例报告讨论了这一介入心脏病学新方法的适应证、技术及并发症原则。
