Left ventricular stent-graft implantation for severe left ventricular outflow tract obstruction after transcatheter mitral valve implantation.

Left ventricular outflow tract obstruction is a rare complication following transcatheter mitral valve implantation. Diagnosing the underlying cause is mandatory to select from different treatment options. We report a case of stent-graft implantation into the left ventricular outflow tract for dynamic left ventricular outflow tract obstruction caused by systolic anterior motion of the anterior mitral valve leaflet (SAM).
