Abstract

Left ventricular outflow tract obstruction (LVOTO) can complicate percutaneous mitral valve replacement and may preclude patients considered high surgical risk from transcatheter therapies. We report a case of mitral valve-in-valve procedure in a patient at high risk for LVOTO. (Level of Difficulty: Advanced.).
