The HeartMate II is a continuous-flow left ventricular assist device that can be explanted from patients after cardiac recovery. We implanted a HeartMate II in a 21-year-old man who had idiopathic cardiomyopathy. A year later, he developed thyrotoxicosis, presumably secondary to amiodarone administered for ventricular fibrillation. Four months after the diagnosis of thyrotoxicosis, thyroid hormone levels had returned to normal, and native cardiac function had improved remarkably. After a support period of 24 months, the HeartMate II was explanted. Six years later, the patient continues to be in New York Heart Association functional Class I. Amiodarone-induced thyrotoxicosis may have contributed to myocardial recovery.
HeartMate II 是一种持续血流左心室辅助装置，可在心功能恢复后从患者体内取出。我们为一名 21 岁的男性植入了 HeartMate II，该男性患有特发性扩张型心肌病。一年后，他出现甲状腺毒症，可能是由于胺碘酮治疗室颤导致的。甲状腺毒症诊断后 4 个月，甲状腺激素水平恢复正常，且心脏固有功能显著改善。辅助治疗 24 个月后，取出了 HeartMate II。6 年后，患者仍处于纽约心脏病协会心功能分级 I 级。胺碘酮诱导的甲状腺毒症可能有助于心肌恢复。
