Abstract

Left ventricular assist devices (LVADs) improve symptoms and outcomes in patients with advanced heart failure. We report the case of a patient with a freshly implanted HeartMate 3 LVAD, suffering abruptly on postoperative day 55 from pejoration of his heart failure with multiple episodes of low-flow alarm. Outflow graft obstruction (OGO) due to local aortic dissection was diagnosed with multimodality imaging. After a multidisciplinary discussion, a surgical approach was decided, and the patient benefited from a revision of his outflow graft.

植入左心室辅助装置（HeartMate 3）后因局部主动脉夹层导致流出管道阻塞。

左心室辅助装置（LVAD）可改善晚期心力衰竭患者的症状和预后。我们报告了一例刚植入 HeartMate 3 LVAD 的患者的病例，他在术后第 55 天突然出现心衰峰值，并伴有多次低流量报警。经多模态成像检查，诊断为局部主动脉夹层导致的流出移植阻塞（OGO）。经过多学科讨论后，决定采用手术治疗，患者从流出道移植物修补术中获益匪浅。
