Introduction

Transcatheter aortic valve implantation (TAVI) in patients with bicuspid aortic valves (BAV) may be associated with suboptimal procedural and clinical outcomes due to inappropriate prosthesis sizing, anatomical difficulties or technical factors1. The narrowest part of the aortic root in BAV anatomy is evident at the supra-annular (SA) level, across the aortic valve leaflets, instead of the annular virtual basal ring (VBR)2. The main objective of our study was to identify a supra-annular plane in the pre-TAVI cardiac computed tomography (CT) scan that might predict the level of valve prosthesis anchoring in raphe-type BAV patients.
