Abstract

A 47-year-old woman with dilated cardiomyopathy underwent HeartMate II (HM2) implantation as a bridge-to-transplantation. Her postoperative course was good. However, 2.5 years after surgery, the outflow graft was found to be twisted and the graft and pump was exchanged. While HeartMate 3(HM3) twisting of the outflow graft is well documented, such malfunctions in HM2 are almost unknown. Although HM2 has since been discontinued, there are a significant number of patients using HM2 who are awaiting heart transplants or destination therapy. We caution that, even with HM2, the possibility of late-phase twisting requires vigilance.

植入 2.5 年后，HeartMate II 流出移植物发生扭曲-HM2 仍在进行中。

一名 47 岁的扩张型心肌病患者接受了 HeartMate II（HM2）植入手术，作为移植前的过渡。她的术后情况良好。然而，术后 2.5 年，发现流出移植体扭曲，于是更换了移植体和泵。HeartMate 3（HM3）流出移植物扭曲的情况有据可查，而 HM2 出现这种故障几乎无人知晓。虽然 HM2 已经停产，但仍有大量使用 HM2 的患者在等待心脏移植或目的地治疗。我们提醒，即使使用 HM2，也需要警惕晚期扭曲的可能性。

期刊介绍： The aim of the Journal of Artificial Organs is to introduce to colleagues worldwide a broad spectrum of important new achievements in the field of artificial organs, ranging from fundamental research to clinical applications. The scope of the Journal of Artificial Organs encompasses but is not restricted to blood purification, cardiovascular intervention, biomaterials, and artificial metabolic organs. Additionally, the journal will cover technical and industrial innovations. Membership in the Japanese Society for Artificial Organs is not a prerequisite for submission.
