Abstract

Transcatheter mitral valve implantation (TMVI) is a relatively novel intervention used to replace the mitral valve of individuals deemed too high risk or unsuitable for surgery. It is associated with a number of specific risks, including left ventricular outflow tract obstruction (LVOTO). In this video tutorial we present the case of a 75-year-old man who was unable to undergo redo surgical repair and had a number of risk factors for LVOTO. To minimize these risks, we deployed the TMVI within the anterior mitral valve leaflet. The postoperative result was mild mitral valve regurgitation and no LVOTO. The long-term outcome of this approach is yet to be determined but we believe this technique offers a novel method to manage a select group of patients suffering with mitral valve disease and at risk of LVOTO.
