Transaortic transcatheter aortic valve implantation: potential issues associated with the use of the ASCENDRA transapical delivery system.

Transaortic transcatheter aortic valve implantation (TAo-TAVI) has been recently proposed as an alternative to transapical (TA) and transfemoral (TF) approach. We now discuss a technical issue associated with TAo-TAVI related to the use of a delivery system dedicated to the antegrade TA approach. The potential solutions to this issue as well as the potential advantages of the TAo approach are discussed.
