Coronary artery bypass grafting prolongs survival in patients with left main coronary artery stenosis. However, this benefit is denied to patients who refuse the procedure or who are poor surgical candidates due to comorbid conditions. We describe a novel technique for the percutaneous revascularization of stenosis in an unprotected left main coronary artery in high-risk patients. The TandemHeart, a percutaneously inserted left ventricular assist device, was used to provide periprocedural hemodynamic support during angioplasty and stenting of an unprotected left main coronary artery for stenosis in a 70-year-old woman. The device was removed immediately after the procedure, and the patient was discharged from the hospital on the 2nd postprocedural day. The potential advantages of angioplasty with the support of percutaneous left ventricular assist devices in high-risk patients are discussed.
冠状动脉搭桥术可延长左主干冠状动脉狭窄患者的生存期。然而，拒绝接受该手术或因合并症而不适合手术的患者无法从中获益。我们描述了一种用于高危患者非保护左主干冠状动脉狭窄经皮血管重建的新技术。在一名70岁女性患者非保护左主干冠状动脉狭窄的血管成形术和支架置入过程中，使用经皮插入的左心室辅助装置TandemHeart提供围手术期血流动力学支持。术后该装置立即移除，患者在术后第2天出院。文中讨论了在高危患者中使用经皮左心室辅助装置支持进行血管成形术的潜在优势。
