  • Transcatheter Aortic Valve Replacement for a Failed Mechanical Aortic Prosthesis
    The Annals of thoracic surgery, 2018
    Co-Authors: Joseph Nader, Jean-michel Paradis, Omar Zainulabdin, François Dagenais, Siamak Mohammadi, Dimitri Kalavrouziotis

    Abstract:

    The options for reoperation for a dysfunctional mechanical Aortic Prosthesis in a small Aortic root may be limited for high-risk patients. This report describes a case in which transcatheter Aortic valve replacement was used through the open aorta on cardiopulmonary bypass to minimize operative duration and reduce the risk of Prosthesis-patient mismatch in a patient who was a Jehovah’s Witness with a failed 17-mm mechanical Aortic Prosthesis.

  • management of acute left main obstruction after transcatheter Aortic valve replacement the tunnel technique
    Cardiovascular Revascularization Medicine, 2012
    Co-Authors: Claudia Fiorina, Salvatore Curello, Diego Maffeo, Roberto Lorusso, Giuliano Chizzola, Federica Ettori

    Abstract:

    Two cases of acute left main (LM) obstruction complicating transcatheter Aortic valve replacement (TAVR) and their management are reported. TAVR with a self-expandable transcatheter Aortic Prosthesis was performed for treating severe Aortic stenosis with small Aortic root and severe Aortic regurgitation of a degenerated stentless bioProsthesis, respectively. Left main coronary obstruction occurred at a different time from the index procedure. A novel stent-based angioplasty treatment, denominated “the tunnel technique,” was successfully applied in both cases and herein described.
