We describe the case of a teenage girl with anthracycline-induced cardiomyopathy who received a HeartWare ventricular assist device and underwent successful device explantation after cardiac recovery. During device support, the patient's cardiac function returned to normal. Twelve months after implantation, we explanted the device via repeat median sternotomy. To close the hole in the left ventricular apex and preserve the sewing ring in case future device support is needed, we used a German-manufactured titanium plug, developed specifically for this purpose. To our knowledge, this is the first use of this plug in the United States. The patient recovered uneventfully and was discharged from the hospital on postoperative day 11. Left ventricular biopsy specimens at explantation revealed the resolution of previous degenerative sarcomeric changes. Our patient did well clinically; however, recurrent late anthracycline cardiotoxicity might subsequently cause her cardiac function to deteriorate. In this event, our use of the titanium plug to preserve the left ventricular sewing ring would enable easier device replacement than would other explantation options.
我们描述了一名患有蒽环类药物诱导的心肌病的少女病例,她接受了HeartWare心室辅助装置,并在心脏恢复后成功进行了装置移除。在装置支持期间,患者的心功能恢复正常。植入后12个月,我们通过再次正中胸骨切开术移除了该装置。为了封闭左心室心尖的孔洞并保留缝合环以备将来需要装置支持,我们使用了专门为此目的开发的德国制造的钛塞。据我们所知,这是该钛塞在美国的首次使用。患者恢复顺利,术后第11天出院。移除装置时的左心室活检标本显示先前的退行性肌节变化已消退。我们的患者临床情况良好;然而,蒽环类药物后期复发性心脏毒性可能随后导致她的心功能恶化。在这种情况下,我们使用钛塞保留左心室缝合环将比其他移除选项更便于装置更换。
