Abstract

Left ventricular outflow tract obstruction represents a life-threatening complication in patients undergoing transcatheter mitral valve replacement. Interventional approaches to prevent left ventricular outflow tract obstruction are complex and require exceptional procedural expertise. We demonstrate feasibility and safety of first-in-human device-mediated mechanical laceration of the anterior mitral valve leaflet prior to transapical transcatheter mitral valve replacement. (Level of Difficulty: Advanced.)
