Key result
Percutaneous electrosurgery-guided perforation and balloon dilation of the anterior mitral leaflet was demonstrated in a first-in-human case to prevent LVOTO during transcatheter valve implantation.
Why the study?
Valve-in-mitral annular calcification presents a major challenge due to the risk of left ventricular outflow tract obstruction.
Does percutaneous electrosurgery-guided perforation and balloon dilation of the anterior mitral valve leaflet prevent LVOTO during transcatheter mitral valve replacement in patients with mitral annular calcification?
Does percutaneous electrosurgery-guided perforation and balloon dilation of the anterior mitral valve leaflet prevent LVOTO during transcatheter mitral valve replacement in patients with mitral annular calcification?
This first-in-human report demonstrates a novel percutaneous electrosurgery-guided leaflet modification technique to prevent LVOTO during transcatheter mitral valve replacement in severe mitral annular calcification.
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.
