Hypertrophic cardiomyopathy is known to be difficult to support by left ventricular assist device because of the small ventricular cavity and inadequate drainage. Therefore, instead of cannulating on the left ventricular apex, a HeartWare ventricular assist device (HeartWare, Framingham, MA) was connected to the left atrium through right atrium onto atrial septum using ringed Gore-Tex (W.L. Gore & Associates, Flagstaff, AZ) interposition graft. The patient has been discharged home after ventricular assist device implant and underwent successful heart transplant after 111 days of support without any complications including any thromboembolic events. This new transatrial left atrial cannulation technique can be an alternative approach for ventricular assist device cannulation in hypertrophic cardiomyopathy. It can be safely performed with the HeartWare ventricular assist device.
肥厚型心肌病的心室腔较小，引流不足，因此使用左心室辅助装置支持较为困难。因此，我们没有在左心室心尖部位插管，而是使用带环戈尔补片（戈尔公司，Flagstaff，AZ）将 HeartWare 心室辅助装置（HeartWare，马萨诸塞州弗雷明汉）从右心房连接到左心房，穿过房间隔。患者在植入左心室辅助装置后出院，在没有任何并发症（包括任何血栓栓塞事件）的情况下接受支持 111 天后成功进行了心脏移植。这种新的经房间隔左心房插管技术可为肥厚型心肌病的左心室辅助装置插管提供一种替代方法。它可以与 HeartWare 心室辅助装置安全地进行。
