Transcatheter implantation of balloon expandable valves in native mitral valves (MV) has been performed in patients with severe MV annular calcification who are not good candidates for standard surgical MV replacement. Significant left ventricular outflow tract (LVOT) obstruction with hemodynamic compromise has been described as one of the potential complications of transcatheter MV replacement. Surgical rescue carries significant risk in this high-risk patient population. We describe a percutaneous technique to acutely decrease transcatheter MV replacement-induced LVOT obstruction. © 2016 Wiley Periodicals, Inc.
