In transaortic (TAo) trasncatheter aortic valve implantation (TAVI), direct transmission of forces to the stenotic aortic valve is possible. Therefore, the need of balloon aortic valvoplasty in TAo-TAVI may be very limited regarding the deliverability of TAVI prosthesis. However, if the TAVI prosthesis becomes undeliverable, it becomes seriously problematic. Herein, we present a case of TAo-TAVI in which the TAVI prosthesis was undeliverable, and it was forcefully pushed together with the introducer system into the aortic valve as a bailout technique.
在经主动脉（TAo）经导管主动脉瓣植入术（TAVI）中，有可能将力量直接传递至狭窄的主动脉瓣。因此，就TAVI假体的可输送性而言，TAo-TAVI中球囊主动脉瓣成形术的需求可能非常有限。然而，如果TAVI假体无法输送，就会成为严重问题。在此，我们报告一例TAo-TAVI病例，其中TAVI假体无法输送，作为一种补救技术，将其与导入系统一起强行推送至主动脉瓣。
