We report the dislocation of a stented aortic valve prosthesis two weeks after the uneventful transapical implantation in a female who had underwent mitral valve replacement and CABG six years before. The initial implantation of the Edwards Sapien aortic valve prosthesis (Edwards Lifesciences, Irvine, CA), as well as the postoperative recovery, was uneventfully. At the sixth postoperative day, the patient developed a progressive heart failure due to a severe aortic insufficiency. During conventional aortic valve replacement, the dislocated prosthesis was found in the left ventricle. After uncomplicated postoperative recovery, the patient could be discharged in a good physical condition. Preexisting mitral valve prosthesis seems to be an important, complicating goal for transcatheter aortic valve implantation.
我们报告了一例女性患者在二尖瓣置换和冠状动脉旁路移植术后 6 年后,经心尖途径植入主动脉瓣支架后 2 周发生主动脉瓣假体脱位。Edwards Sapien 主动脉瓣假体(爱德华生命科学公司,欧文,加利福尼亚州)的初始植入以及术后恢复均顺利。术后第 6 天,患者因严重主动脉瓣关闭不全而发生进行性心力衰竭。在常规主动脉瓣置换术中,发现脱位的假体位于左心室。在术后恢复顺利后,患者可以在良好的身体状况下出院。先前存在的二尖瓣假体似乎是经导管主动脉瓣植入术的一个重要的、复杂的目标。
