We report transcatheter aortic valve implantation (TAVI) for pure aortic valve insufficiency in a patient with an otherwise normal aortic valve and a long-term left ventricular assist device (LVAD). An oversized 29-mm Edwards SAPIEN valve (Edwards Lifesciences, Irvine, CA) was implanted in the 21-mm native aortic valve annulus. Despite the complete absence of aortic calcifications, the prosthesis remained stably anchored inside the annulus. The reported experience demonstrates that TAVI is feasible even in patients with pure aortic valve regurgitation and can be a reasonable option in patients with aortic regurgitation after LVAD implantation.
我们报告了一例经导管主动脉瓣植入术（TAVI）用于治疗主动脉瓣无明显病变但长期使用左心室辅助装置（LVAD）的患者的单纯主动脉瓣关闭不全。在 21 毫米的原生主动脉瓣环中植入了一个过大的 29 毫米爱德华 Sapien 瓣膜（爱德华生命科学公司，欧文，加利福尼亚州）。尽管没有主动脉钙化，但假体仍然稳定地锚定于瓣环内。报告的经验表明，即使对于单纯主动脉瓣反流的患者，TAVI 也是可行的，对于 LVAD 植入后出现主动脉瓣反流的患者，TAVI 也是一种合理的选择。
