  • Title: Difficulties with horizontal aortic root in transcatheter aortic valve implantation.
    Author: Chan PH, Alegria-Barrero E, Di Mario C.
    Journal: Catheter Cardiovasc Interv; 2013 Mar; 81(4):630-5. PubMed ID: 22431290.
    Abstract:
    Transcatheter aortic valve implantation (TAVI) emerged to be a viable treatment option for failing bioprosthesis in the aortic position. Transfemoral approach is the most common access route for TAVI and associated with most favorable clinical outcome. However, in the presence of unfavorable aortic root anatomy, TAVI via transfemoral approach provides inadequate support for device manipulation during valve positioning, particularly performed for the indication of severe aortic regurgitation. We report our experience on TAVI utilizing CoreValve for a patient with regurgitant failing bioprosthesis with horizontal aortic root where we encountered difficulties during implantation and retrieval of valve delivery system.
