Transcatheter aortic valve replacement (TAVR) for bicuspid aortic valve stenosis is challenging, and the absence of established methods for sizing the bicuspid aortic valve (BAV) complicates TAVR. We report a case of successful TAVR for bicuspid aortic stenosis with a severely calcified raphe. We used an undersized SAPIEN 3 valve, with three safety measures based on assessment of structural characteristics, sizing by the circle method, and deployment of the valve by the pressure-regulated method.
经导管主动脉瓣置换术（TAVR）治疗二叶式主动脉瓣狭窄具有挑战性，且缺乏成熟的二叶式主动脉瓣（BAV）尺寸测量方法使TAVR变得复杂。我们报告了一例成功使用TAVR治疗伴有严重钙化嵴的二叶式主动脉瓣狭窄的病例。我们使用了尺寸偏小的SAPIEN 3瓣膜，并基于结构特征评估、采用圆周法测量尺寸以及通过压力调节法进行瓣膜植入这三种安全措施。
