Abstract

Left ventricular assist devices (LVAD) are frequently used in the management of end-stage heart failure, especially given the limited availability of donor hearts. The latest HeartMate 3 LVAD delivers non-physiological continuous flow (CF), although the impact on the aorta is not well established. We highlight a case of aortic aneurysm formation complicated by dissection formation that necessitated high-risk re-operative surgery in a patient post CF-LVAD.

摘要

左心室辅助装置（LVAD）常用于治疗终末期心力衰竭，尤其是在供心有限的情况下。最新的 HeartMate 3 LVAD 提供非生理的连续血流（CF），尽管其对主动脉的影响尚未得到充分证实。我们重点介绍了一例 CF-LVAD 后患者发生的复杂主动脉瘤形成伴夹层形成的病例，需要进行高风险的再次手术。
