The presence of a mechanical aortic valve prosthesis is considered a relative contraindication for left ventricular assist device implantation (LVAD) due to the occurrence of thromboembolic events. Five patients were operated on for LVAD implantation with status post mechanical aortic valve implantation (n = 3 with status post Bentall procedure). After removal of the leaflets, a transcatheter balloon-expandable valve was placed within the mechanical ring in all patients. Three patients were discharged from hospital with a maximum follow-up of 3.3 years. Transaortic transcatheter valve implantation into a mechanical aortic valve during LVAD implantation is a feasible option. It reduces operative times and might also prevent thromboembolic events.

在左心室辅助装置植入期间直接经主动脉经导管瓣中瓣植入机械主动脉瓣假体：手术技术的描述。

由于血栓栓塞事件的发生，机械主动脉瓣的存在被认为是左心室辅助装置植入 (LVAD) 的相对禁忌症。5 名患者进行了 LVAD 植入手术，机械主动脉瓣植入后状态（n = 3，Bentall 手术后状态）。取出小叶后，所有患者的机械环内均放置了经导管球囊扩张瓣膜。3例患者出院，最长随访3.3年。在 LVAD 植入期间经主动脉经导管瓣膜植入机械主动脉瓣是一种可行的选择。它减少了手术时间，还可以预防血栓栓塞事件。
