We present the patient with severe aortic insufficiency (AI) 5 years post left ventricular assist device (LVAD) implantation. His management was complicated with unsuccessful percutaneous aortic valve closure attempt, transcatheter aortic valve replacement (TAVR) implantation with a severe paravalvular leak, eventual valve dislodgment into the left ventricle (LV), and LVAD inflow cannula occlusion. We utilized a mini-thoracotomy approach to successfully retrieve the dislodged valve through the LV apex while deploying a valve-in-valve TAVR under direct visualization and deep hypothermic cardiac arrest. This case can serve as an example of the serious pitfalls and potential resolution strategies when treating LVAD-associated AI.
我们报告了1例左心室辅助装置(LVAD)植入术后5年出现严重主动脉瓣关闭不全(AI)的患者。其治疗过程复杂,经皮主动脉瓣关闭尝试失败,经导管主动脉瓣置换术(TAVR)植入后出现严重瓣周漏,最终瓣膜移位至左心室(LV),且LVAD流入插管闭塞。我们采用微创开胸手术方法,在直接可视化和深度低温心脏停搏下,通过左心室心尖成功取出移位的瓣膜,同时植入瓣中瓣TAVR。该病例可作为治疗LVAD相关AI时严重陷阱及潜在解决策略的一个实例。
