Left ventricular unloading during extracorporeal life support aims to minimize potential side effects of increased left ventricular afterload. A transaortic catheter vent implanted through a subclavian approach was used in 2 patients. Patient 1 was a 48-year-old man with a recent history of ST-elevation myocardial infarction who developed refractory cardiogenic shock due to severe biventricular dysfunction. Patient 2 was a 56-year-old man admitted for severe flu. The unloading procedure was successful in both patients, with bridge to heart transplantation in the first case and bridge to recovery in the other.
体外生命支持期间的左心室卸载旨在将增加左心室后负荷的潜在副作用降到最低。通过锁骨下入路植入的经主动脉导管心排出量辅助装置被用于 2 名患者。患者 1 是一名 48 岁男性，近期有 ST 段抬高型心肌梗死病史，因严重双心室功能障碍而出现难治性心源性休克。患者 2 是一名 56 岁男性，因严重流感入院。在这 2 名患者中，卸载过程均成功，第 1 例患者通过桥接进行心脏移植，第 2 例患者通过桥接恢复。
