The Impella 5.5 with SmartAssist system (Abiomed, Danvers, MA) is approved for the treatment of cardiogenic shock after acute myocardial infarction, cardiac surgery, or in the setting of cardiomyopathy. Designed for full circulatory support and left ventricular unloading the system comprises a catheter-based microaxial pump placed across the aortic valve, pulling blood from the left ventricle and into the ascending aorta. Implantation can be approached through the axillary artery or directly into the aortic root. We present several technical options for implanting, tunneling, and explanting the system using the direct aortic approach and allowing for bedside removal.
Impella 5.5 与 SmartAssist 系统(Abiomed,马萨诸塞州丹弗斯)获准用于治疗急性心肌梗死后、心脏手术后或心肌病引起的心源性休克。该系统旨在提供全面循环支持和左心室卸载,由一个经导管的微型轴流泵组成,该泵穿过主动脉瓣,将血液从左心室泵入升主动脉。可以通过腋动脉或直接进入主动脉根部进行植入。我们提出了几种使用直接主动脉入路植入、隧道和取出该系统的技术选择,并允许在床边移除。
