An outflow graft obstruction impairing the blood flow is a complication of a left ventricular assist device therapy due to thrombosis as the most common cause. We describe a rare case of a patient who presented with a new low-flow alarm after 7 years of uneventful left ventricular assist device support with Heartmate II device. Computed tomography and surgical exploration revealed an obstruction caused by a twist of the outflow graft. A successful surgical repair without the use of cardiopulmonary bypass could be performed and resulted in immediate relief of symptoms.
左心室辅助装置治疗后发生血栓形成是导致流出道移植物阻塞、血液流动受损的并发症，这也是最常见的原因。我们描述了一例罕见病例，该患者在使用 Heartmate II 装置成功进行左心室辅助装置支持 7 年后，出现新的低流量报警。计算机断层扫描和手术探查显示流出道移植物扭转导致阻塞。成功进行了无需体外循环的手术修复，症状立即得到缓解。
