背景：二叶式主动脉瓣 (BAV) 中经导管主动脉瓣植入的尺寸仍然存在争议。方法和结果：BAVARD（二叶式主动脉瓣解剖和与装置的关系）回顾性登记的目的是捕获 BAV 中经导管主动脉瓣植入的尺寸比率，并分析植入后第二代假体的几何形状。将大约 101 名 BAV 患者以及可用的经导管主动脉瓣植入前后多探测器计算机断层扫描与 88 名三尖瓣主动脉瓣 (TAV) 患者进行了比较。术前多排计算机断层扫描诊断出 0 型和 1 型 BAV 的比例分别为 12.9% 和 86.1%。基线时，BAV 和 TAV 患者的椭圆率指数相似：1.2 +/- 0.1 与 1.2 +/- 0.1，P=0.09。平均环形尺寸过大分别为 1.14 +/- 0.04 和 1.04 +/- 0.04，P
BACKGROUND: Sizing for transcatheter aortic valve implantation in bicuspid aortic valves (BAV) remains controversial.METHODS AND RESULTS: The aim of the BAVARD (Bicuspid Aortic Valve Anatomy and Relationship With Devices) retrospective registry is to capture the sizing ratios used for transcatheter aortic valve implantation in BAV and analyze the second-generation prostheses geometry postimplantation. About 101 patients with BAV along with available preand post-transcatheter aortic valve implantation multidetector computed tomography were compared with 88 tricuspid aortic valves (TAV) patients. Preprocedural multidetector computed tomography diagnosed type 0 and type 1 BAV in, respectively, 12.9% and 86.1 % of BAV. At baseline, the ellipticity index was similar between BAV and TAV patients: 1.2 +/- 0.1 versus 1.2 +/- 0.1, P=0.09. The mean annular oversizing was, respectively, 1.14 +/- 0.04 and 1.04 +/- 0.04, P
