HeartMate II (Thoratec Corp, Pleasanton, CA) continuous-flow ventricular assist devices may be exchanged through a subcostal approach, where the device body can be accessed easily and safely. The existing bend relief needs to be reattached to the new device body at the end of the operation, and this reattachment often results in a malalignment between the outflow graft, the bend relief, and the device body. This causes unexpected detachment and subsequent graft kinking. We present a new, simple technique to reinforce the bend relief connection.
HeartMate II（Thoratec 公司，加利福尼亚州普莱森顿）连续流心室辅助装置可通过肋缘下入路进行更换，该入路可方便且安全地触及装置主体。在手术结束时，需要将现有的弯曲缓解装置重新连接到新的装置主体上，而这种重新连接通常会导致流出移植物、弯曲缓解装置和装置主体之间的不对准。这会导致意外脱离和随后的移植物扭结。我们提出了一种新的、简单的技术来加强弯曲缓解装置的连接。
