[Transcatheter aortic valve implantation in bicuspid aortic valve: never say never]

Transcatheter aortic valve implantation (TAVI) is an emerging alternative technique that has shown promise in the treatment of severe aortic stenosis in patient populations at high risk with conventional surgery. The presence of a bicuspid aortic valve (BAV) has been considered an exclusion criterion for TAVI, because of the presumed risk for poor seating or paravalvular regurgitation due to severe distortion of the native valve leaflets. For this reason, BAV disease has generally been an exclusion criterion in major trials of TAVI and there is little clinical experience available. We report a case of transcatheter valve replacement in a poor surgical candidate with BAV stenosis using a new 29 mm Edwards Sapien prosthesis.
