Abstract

Valve-in-mitral annular calcification presents a great challenge with a risk of left ventricular outflow tract obstruction (LVOTO). We demonstrate the first-in-human experience of performing percutaneous electrosurgery-guided perforation and balloon dilation of the anterior mitral valve leaflet followed by transcatheter valve implantation to prevent LVOTO.

Keywords: anterior mitral valve leaflet modification; electrosurgery; left ventricular outflow obstruction; valve-in-MAC.
