The successful treatment of acute decompensated heart failure continues to evolve with an increasing utilization of nondurable mechanical support devices. Indications for acute support have broadened to include their use as a bridge to recovery or decision (for durable ventricular assist devices [VADs] or heart transplant). Available devices have improved in terms of effectiveness, ease of insertion, and reduction in complications. The commonly used devices (intra-aortic balloon pump, TandemHeart, Impella, and extracorporeal membrane oxygenation circuit), together with their mechanisms of action, are reviewed. Current considerations for support, specific to each device, are examined and future directions and indications for percutaneous VADs are explored.
随着非持久性机械支持设备使用的增加，急性失代偿性心力衰竭的成功治疗方法也在不断发展。急性支持的适应症已经扩大，包括将其用作恢复或决策（针对持久性心室辅助装置[VAD]或心脏移植）的桥梁。现有设备在有效性、插入便利性和并发症减少方面都有了改进。本文综述了常用设备（主动脉内球囊泵、TandemHeart、Impella和体外膜肺氧合回路）及其作用机制。研究了每种设备特有的当前支持考量因素，并探讨了经皮VAD的未来方向和适应症。
