Trans-right subclavian TAVI presents technical challenges regarding device coaxiality due to anatomical orientation.
Background: Trans-subclavian access transcatheter aortic valve implantation (TAVI), typically from the left side, is feasible. However, right subclavian artery access is technically challenging because of the anatomical orientation, resulting in malalignment of the transcatheter heart valve within the aortic annular plane.
Hamada et al. (Wed,) studied this question.
