  • Title: Management of acute left main obstruction after transcatheter aortic valve replacement: the "tunnel technique".
    Author: Fiorina C, Curello S, Maffeo D, Lorusso R, Chizzola G, Ettori F.
    Journal: Cardiovasc Revasc Med; 2012; 13(2):142.e5-9. PubMed ID: 22093592.
    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.
