Alcohol septal ablation for outflow tract obstruction after transcatheter aortic and mitral valve replacement: Alcohol septal ablation for outflow tract obstruction after transcatheter aortic and mitral valve replacement

Left ventricular outflow obstruction after transcatheter mitral valve replacement is a life-threatening complication. We report a case of a 68-year old female with early degeneration of a transcatheter aortic valve and severely calcified mitral valve stenosis who was considered inoperable by a multidisciplinary heart team and referred for transcatheter aortic and mitral valve replacement. Our aim is to report the planning, procedural aspects, and management of device-related left-ventricular outflow tract obstruction after transcatheter double valve replacement.
