TAVR in bicuspid aortic valve (BAV) represents a challenging scenario. Valve sizing and positioning are the most important determinants of procedural success. In BAV the maximal prosthesis-anatomy interference occurs at the supra-annular level. Supra-annular prosthesis implantation may improve valve sealing and hemodynamic result. In this case series, we propose a new site for prosthesis implantation, guided CT scan supra-annular sizing for BAV undergoing TAVR.
经导管主动脉瓣置换术（TAVR）在二叶式主动脉瓣（BAV）中代表了一种具有挑战性的情况。瓣膜尺寸和定位是手术成功的最重要决定因素。在 BAV 中，最大的假体-解剖结构干扰发生在上瓣环水平。瓣上环植入假体可改善瓣膜密封和血流动力学效果。在本病例系列中，我们提出了一种新的假体植入部位，并对行 TAVR 的 BAV 进行 CT 引导的瓣上环尺寸测量。
